# Parametric Part Scrip Editing

(Available in Platinum)

Default UI Menu: Tools/Palettes/Parametric Part Script Editor Parametric parts (PPM) are defined using a text description (script). The script defines the structure, editable properties, and output that result in a parametrically editable part. The script must be saved with a *.PPM extension. The name of the file determines the name of the part.

Examining a Script

A simple example of a parametric part is a rectangle where the width, height and rotation angle are defined though parameters. The script of such part might look as follows: // Here is a description of simple rectangle. H = Parameter("Height", 5, LINEAR, Interval(0, 100)); L = Parameter("Length", 10, LINEAR, Interval(0, 200)); Angle = Parameter("Angle", 0, ANGULAR, Interval(0, 360)); Rect1 = Rectangle(H, L); Rect = RotateZ(Rect1, Angle); Output(Rect); Let's examine each line of this example: LINE 1 // Here is a description of simple rectangle. The '//' indicates a comment. Comments do not affect the behavior of a part. All text following '//' to the end of the line are contained by the comment. LINE 2 H = Parameter("Height", 5, LINEAR, Interval(0, 100)); The second line specifies the definition of the 'H' parameter. Let's break out each element of the line to define its function: H This is the identifier (name) of the parameter in the part description = The equals sign associates the identifier with its definition Parameter This is a function. 'Parameter' defines that H is a Parameter ( Specifies the start of the Parameter function's properties "Height" The name of the parameter that will appear in the Properties dialog , Indicates the end of one property and the beginning of the next 5 Assigns the default value for H , Separates properties LINEAR Specifies that H is a linear value , Separates properties Interval(0, 100) Specifies the allowable values for H as an interval from 0 to 100 ) Specifies the end of the Parameter function's properties ; End of definition for H LINES 3 – 4 L = Parameter("Length", 10, LINEAR, Interval(0, 200)); Angle = Parameter("Angle", 0, ANGULAR, Interval(0, 360)); The next two lines in the example are similar to the previous one. They define the characteristics of L and Angle parameters in a similar layout. Note that the 'Angle' parameter uses an ANGULAR interval rather than LINEAR. LINE 5 Rect1 = Rectangle(H, L); This line uses the Rectangle function to define a rectangle called 'Rect1'. It uses the previously defined H and L parameters to specify its properties, height and length. The center of this rectangle will be at the world origin (x=0,y=0,z=0) in the drawing. More on the rectangle tool will be covered later. LINE 6 Rect = RotateZ(Rect1, Angle); This line defines a new rectangle called 'Rect' which is a rotated version of 'Rect1', using the Angle parameter to define the rotation. LINE 7 Output(Rect); The last line specifies that the output of the script will be the rotated rectangle called 'Rect'. This is what the be drawn as the part.

Script syntax

The description of a parametric part consists of the entire contents of a text file, except comments, tabs, and other control characters, which are ignored. Comments are specified either using "//" characters that mean that all subsequent characters up to the end of the line are comments, or using the pair "/" and "/" that denote beginning and end of thecomment, respectively. A text description is a set of two types of operators: and ;

Identifiers

The defines the symbolic name of an object. It is a set of Roman letters and Arabic numerals, which must start with a letter. For example valid names would be: PART2a MyPart A134 Object identifiers may not be the same as names of functions or such names as PI, or LINEAR. These are reserved words that are used to designate the constants of the scripting language. The list of all reserved names is provided in the reserved word list which appears at the end of this chapter.

Expressions

Expressions define the associated identifier. Expression syntax matches the expression syntax in the majority of programming languages. They may define numeric value, arithmetic operations, the dependence of the defined object on other objects and function calls. The structure of a function call is: (), Examples of correct expression syntax: (D --1/4) * k; Polyline(Point(0, 0.25 - 1/8), Point(0, D), Arc1(L-C, - m, m), Point(0,0)); A = B + 0.5; B = 7;

Arithmetic Operations

Arithmetic operations may use the standard arithmetical operators '+' (addition), '--'(subtraction), '*' (multiplication), '/' (Division) and parenthesis '('and ')', to determine the sequence of performing arithmetic operations. Object identifiers and numbers serve as operands.

Script Semantics

A script contains full description of a parametric part. The collection of script operators determines which actions need to be performed to create the resultant object(s). Correct understanding of a script, requires having a clear understanding of how its operators are interpreted. Identifiers that are used in a must be defined. In other words it must have been used as: = ; The list of resultant objects is defined in the Output(..) operator. The Output(..) operator contains a list of which objects are to be displayed in the resulting part. This operator must be present in the script. Each object in the list of arguments for Output(..) must be defined. In other words it must have been used as: = ; This operator must be present in the script. At least one object must be listed in the Output operator, but you need not output every object used in the script. The Output operator determines the method that will be used to create an object with this name. A correct script describing a parametric part should conform to the following rules:

• A script may have more than one Output(..) operator, but any should contained in only one Output(..) operator_._
• For each object used in the Output(..) operator there should be one, and only one, instance of any .
• For each object used in an there should be one, and only one, instance of any .
• Each identifier should be used only once as
• Each identifier should be at least once in an operator or in an Output(..)operator_._
• Circular calculation and interdependent referencing are not allowed. The script must not contain interdependent where "Item One" is defined by "Item Two", and "Item Two" is defined by "Item One".

The following situations: A = B + 0.5; B = sin(A); or A = C+5; B = D+42; C = (3(2+A)); D = A/2; are not allowed. The first case A and B define each other directly. In the second case A is defined by B through C, and B is defined by A through D. This also means that an identifier is not allowed to depend on itself. For example, you cannot use an operator of this form: H = H1.05; NOTE: The sequence of script operators is not important (except certain special cases that will be described later); because operators are sorted before the script is run.

Basic Functions

Probably the most significant advantage of this method of creating parametric parts is the compact size and clarity of the text description of parametric parts in script form. The set of basic functions used in such a description, determines the level of clarity and simplicity of scripts for a particular class of parametric parts. Note: It is intended that the set of basic functions will expand from version to version.

Description of Parameters

It is important to understand the structure used to within a Parameter function. Format: = Parameter(, , [, ][, ]..); NOTE: The '<>' markers are used to designate elements in the expression, and the '[ ]' markers are used to indicate elements which are optional.

The name displayed in the user interface;
The default value of the parameter;
Defines the parameter type. The following example values are possible: LINEAR, means that the parameter is a linear value in the selected linear units of measure. ANGULAR, means that the parameter is an angular value in the selected angular units of measure. (only degrees are available at this time) TEXT, a text string; FONT, a font name; COLOR, an RGB color value; MATERIAL, a material name; CHECKBOX, a logical value, either ON or Off
These are optional. They define possible restrictions imposed on parameters. Restrictions can be listed in arbitrary order and may take on the following forms: Set(,...) — a list of permissible values of the parameter Interval(, ) — sets the minimum and maximum values of the parameter; LessThan() — indicates that parameter value should be less than the specified value LessOrEqual() — indicates that parameter value should not be greater than the specified value GreaterThan() — indicates that parameter value should be greater than the specified value GreaterOrEqual() — indicates that parameter value should not be smaller than the specified value Set(FolderList) --- particular case of Set operator, when a list of permissible values are defined by operator FolderList. Restrictions should not contradict each other. For example, you cannot combine GreaterThan(5) with LessThan(2). When specifying parameter restrictions, it is not allowed to use identifiers or expressions that directly or indirectly depend on other parameters, as arguments of the above-mentioned functions. Only constants or constant expressions can be used, for example: LessOrEqual(PI/2).

Example of Parameter Description: Alpha = Parameter("Rotation Angle", 45, ANGULAR, Interval(-90, 90)); // This creates a parameter used to define a rotation angle. The name is 'Rotation Angle', the default is 45, the value type is ANGULAR, and the Interval is from '-90' to '90'

Functions for Creating 2D Entities

The following functions are used to create 2D graphic entities

Circle

The Circle function is used to create circles Format: Circle([, , ]);

, Defines optional arguments that set the (x, y) coordinates of the circle center. By default, cx = 0, cy = 0

Example: N = Circle(D/2, 0, y0); A more extensive example: //circle.ppm – two circles r1 = Parameter("Radius1", 2.5, LINEAR, Interval(0.0, 10.0)); r2 = Parameter("Radius2", 1.25, LINEAR, Interval(0.0, 10.0)); xc = Parameter("CenterX", 3, LINEAR, Interval(-100, 100)); yc = Parameter("CenterY", 3, LINEAR, Interval(-100, 100)); c1 = Circle(r1); // circle centered on the origin c2 = Circle(r2, xc, yc); // circle offset from the origin Output(c1, c2);

Rectangle

The Rectangle function is used to create rectangles. Format: Rectangle(, [, , ]);

Defines the rectangle width
Defines the rectangle height
, Defines optional arguments that set the (x, y) coordinates of the rectangle center. By default, cx = 0, cy = 0

Example: rect = Rectangle(W, H, W/2. H/2); // Left bottom corner is in (0,0) point

Polyline

The Polyline function is used to create polylines consisting of straight line segments and arc segments. Format: Polyline();

Defines the list of arguments, delimited with commas. Arguments define individual segments of a polyline

A line segment is defined by 2 Points. An arc segment is defined with a Fillet function or with an Arc0 or Arc1 function and two Points on the ends of the arc. For polylines that contain only straight line segments, the consists of only 2D points, defined using Point(x,y) function. Format: Point(,)

Defines the x coordinates of the point
Defines the y coordinates of the point

For example, a rectangle can be defined in the following way: rect = Polyline( // no end-of-line is used semicolon here Point(0,0), // since this function in on multiple lines Point(W, 0), Point(W,H), Point(0, H), Point(0,0) ); It should be noted that when a polyline's, first and last points are coincident, is called a closed polyline. This type of polyline bounds a certain area, and can be used for creating 3D objects. Polylines with arc segments are defined by adding auxiliary functions Arc0 and Arc1 to the list of arguments. Arc0 builds the circular arc clockwise, while Arc1 builds the circular arc counterclockwise. Format: Arc0(,), Arc1(,),

Defines the x coordinates of the arc center
Defines the y coordinates of the arc center

The start and end point of an arc are defined by the preceding and the following arguments. Arc0 and Arc1 cannot be the first or last argument in the list of arguments. For a polyline that contains only one arc segment, the consists of 2 Points defined with Point(x,y) function and an arc defined with either the Arc0 or Arc1 function. Example of arc0 and arc1 in a polyline: //Polyarc.ppm – polyline with arcs YSize=5; XSize=6; R = 1; Path = Polyline(Point(0, R), // start at top of rounded lower left corner. Point(0, YSize-R), // go to bottom of rounded top left corner. Arc1(0, YSize, R), // make this corner a "cutout" Point(R, YSize), // left side of top edge Point(XSize-R, YSize), Arc0(XSize-R, YSize-R, R), // make this corner a "fillet" Point(XSize, YSize-R), Point(XSize, R), Arc0(XSize-R, R, R), // another fillet Point(XSize-R, 0), Point(R, 0), Arc1(0, 0, R), // another cutout Point(0, R)); Output(Path); Another method of creating an arc in a polyline is to use the auxiliary function Fillet, which "smooths" two linear segments that start and end in the preceding point, by adding an arc with the specified radius into the corner. This ensures smoothness at the junction points. Format: Fillet();

Defines the radius of the fillet

Example of fillets in a polyline: // polyfillet.ppm – polyline with fillets H = 5; L = 10; FR = 1; p2 = Polyline(// Rectangle with rounded corners Point(0,0), // lower left corner Point(L,0), // lower right corner Fillet(FR), // places fillet at bottom right Point(L,H), // upper right corner Fillet(FR), // places fillet at top right Point(0,H), // upper left corner Fillet(FR), // places fillet at top left Point(0,0), // closes rectangle Fillet(FR) // fillets start/end corner. Since this is a closed shape, // no following Point function is needed. ); Output(p2); Fillet and Arcs can be used together in the same Polyline function. Example of Arcs and Fillet in a polyline: Poly1 = Polyline( // Rectangle with rounded corners Point(0,0), Point(W - r, 0), Arc1(W - r, r), Point(W, r), Point(W, H - r), Arc1(W - r, H - r), Point(W – r ,H), Point(0, H), Fillet(r), Point(0,0), Fillet(r) );

Functions for Creating 3D Entities from 2D Entities

You can use 2D entities as the basis for creating 3D objects.

Thickness

Format: Thickness(, );Defines the initial graphic objectDefines new value of ThicknessExample of Thickness: *RectA = Rectangle(2, 5);* RectThick = Thickness(RectA, 3);* Example of Thickness Used to Create a Box Function: *Input(x0,y0,z0,x1,y1,z1)* R = Rectangle(x1-x0, y1-y0, (x0+x1)/2, (y0+y1)/2);* T = Thickness(R, z1-z0);* Output(Move(T, 0, 0, z0));* Another Example of Thickness: *//thickrect.ppm – draws a 2D rectangle and adds thickness* L = Parameter("Length", 4, LINEAR, Interval(0.1, 20));* W = Parameter("Width", 3, LINEAR, Interval(0.1, 20));* H = Parameter("Height", 1.5, LINEAR, Interval(0.1, 20));* Rect = Rectangle(L, W);* Box = Thickness(Rect, H);* Output(Box);* An Example of Thickness with a Circle: *// thickcircle.ppm – draws a circle and adds thickness* Cylind=Thickness(Circle(1,2,2),2);* Output(Cylind);* An Example of Changing Thickness: *// thickcircle2.ppm – draws a cylinder and changes thickness* Cylind=Thickness(Circle(1,2,2),2);* Cyl2 = Thickness(Cylind, 4); // changes the thickness of the first cylinder* Output(Cyl2);*SweepThe Sweep function creates a 3D object by extruding a specified profile along a path, defined by a 2D polyline or circle. The profile is defined by a closed 2D polyline or circle. Format: *Sweep(, [,]);*This defines the profile using a 2D polylineThis defines the path, along which the profile is "dragged"; the path is defined by a 2D polyline Note: *The plane of the path and the plane of the profile must not be parallel.*This optional argument, defines the rotation angle of the profile relative the Z axis; by default, the argument is equal to zeroExample of Sweep: *Poly1 = Polyline(* Point(0,0),* Point(1, 0),* Point(1,2),* Point(0, 2),* Point(0,0) );* PolyProfile = RotateX(Poly1, 90); // the Rotate function will be explained later* PolyPath = Polyline(* Point(0,0),* Point(10, 0),* Point(10,10),* Point(0, 10),* Point(0,0) );* PolySweep = Sweep(PolyProfile, PolyPath);* Output(PolySweep);* Another Example of Sweep *//sweep1.ppm* R = 2;* D = 5;* C1 = RotateX(Circle(R, D/2+R, 0),90); // profile* C2 = Circle(D/2, 0, 0); // path* Torus = Sweep(C1,C2);* Output(C1, C2, Torus); //C1 and C2 shown for reference* An Extended Example of Sweep *//sweep2.ppm – another sweep example* L = Parameter("Length", 5, LINEAR, Interval(0.005, 1000));* W = Parameter("Width", 3, LINEAR, Interval(0.005, 1000));* H = Parameter("Height", 1, LINEAR, Interval(0.1, 3));* FR = Parameter("Fillet Radius", 0.3, LINEAR, Interval(0.001,100));* p = Polyline(Point(0,0), Point(0,H), Point(-FR,H), Point(-FR,0), Point(0,0));* p1a = RotateX(p,90,0,0);* p1 = Move(p1a, 0, W/2, 0);* p2 = Polyline( Point(0,0), Point(0,W), Fillet(FR), Point(L,W), Fillet(FR), Point(L,0), Fillet(FR), Point(0,0), Fillet(FR));* s = Sweep(p1, p2); Output(s);*Functions for Creating 3D Entities Directly3D object may also be created directly without reference to a 2D entity.SphereThe Sphere function is used to create a 3D sphere.

These transformations are related to the transformation of the coordinate system. As always functions create transformed objects, while original objects do not change.MoveThe Move function is used to move (shift) graphic objects. Format: *Move(, , , [,count]);Defines the original graphic object, ,Defines value of movement along x, y and z axes, respectivelyDefines the number of created objects, where each subsequent object is created by moving the preceding object; this argument is optional, with the default value of 1Example of Move: *PolyProfile = Move(Poly1, 1, 3);* Another Example: *//move.ppm – illustrates the Move function* *RB = Parameter("BaseRadius", 2, LINEAR, Interval(0.1, 10));* *RT = Parameter("TopRadius", 0.5, LINEAR, Interval(0, 10));* *H = Parameter("Height", 4, LINEAR, Interval(0.1, 20));* *con1 = Cone(H, RB, RT);* *cx = Parameter("CenterX", 5, LINEAR, Interval(-10, 10));* *cy = Parameter("CenterY", 0, LINEAR, Interval(-10, 10));* *cz = Parameter("CenterZ", 0, LINEAR, Interval(-10, 10));* *count = Parameter("Copies", 2, LINEAR, Interval(1, 10));* *con2 = Move(con1, cx, cy, cz, count);// create count copies, offsetting each by cx, cy, cz* *Output(con1, con2);*RotateThe RotateX, RotateY.

The files must be importable (supported) by the CAD system, such as *.TCW,* .DWG, *.SKPStaticSymbolThe StaticSymbol function loads non-parametric symbols from external files. When the external symbol's filename is specified with no path information, the symbol is automatically assumed to reside in a sub-folder named Macro that is located in the ppm file's home folder. Format: *StaticSymbol([,BlockName]);*Defines the file name with extension. If the extension is not specified, native file format will be usedThis is an optional argument, which indicates that only the block with the given name should be used as the symbol for loading, and the rest of the contents should be ignored; if the argument is not defined, the active drawing will be loaded as a symbolExample of StaticSymbol: *//staticsym1.ppm – loads an external file from the Macro sub-folder* *S = StaticSymbol("ExternalSymbol.tcw");* *Output(S); //static symbol from ExternalSymbol.tcw file is inserted on the drawing*Set(FolderList(...))To create a list of files in a folder, Set(FolderList(...)) is typically used as the Parameter restriction. Format: *= FolderList( = "*.ppm");*Defines the path to the folder from which the list of files will be createdDefines the mask of file names and extensionsExample of Set(FolderList(..)): *// staticsym2.ppm – loads an external symbol from a different folder than Macro* *DrawingName = Parameter("Drawing", "Drawing1", Set(FolderList("......\Drawings", "*.tcw")));//quantity of "....\" (before folder Drawings) is equal to quantity* *//of steps over folder tree starting from the Macro sub-folder.* *S0 = StaticSymbol("......\Drawings\"DrawingName".tcw");* *//here a static symbol is loaded from a file with a tcw-extension,* *// and a filename picked from the FolderList obtained via the DrawingName parameter.* *Output(S0);* When specifying a relative path, you must remember that the path is always assumed to start, not at the folder that contains the ppm file, but in a folder below that named "Macro". In the example above, assume for the moment that staticsym2.ppm is located in: *C:\Users\Me\Documents\MyCAD\PPM Documentation Samples* The path used in the FolderList path and the StaticSymbol path must then implicitly begin at *C:\Users\Me\Documents\MyCAD\PPM Documentation Samples\Macro* The external symbol is being loaded from: *C:\Users\Me\Documents\MyCAD\Drawings* That means the script must navigate up three directories to the MyCAD folder, then back down one level to the Drawings folder, so the correct relative path is: ......\Drawings Another example, which loads a specific .tcw file from the Drawings folder: *//staticsym3.ppm – loads a specific file from a different folder* *S = StaticSymbol("......\Drawings\3DSliceTest.tcw");* *//only loads the specific file 3DSliceTEst.tcw.* *//Remember that the relative path is still rooted in the Macro subfolder.* *Output(S);* A parametric part (a file with a *.ppm extension) can loaded by calling the name of the parametric file as if it were a function, whose arguments are the parameters of the part to be loaded, in the order in which they are described in the file. Refer to "Creating Custom Functions" below for more details on this process.Functions for 3D Boolean OperationsFunctions of this class are used to perform Boolean operations on 3D geometric objects.BooleanUnionThe BooleanUnion function creates an object by adding the specified objects together.

Format: *G3Fillet(,, );Defines the 3D object whose edges are to be roundedDefines the edge or multiple edges, which are to be filleted. Each edge is defined by Point(xc,yc,zc) or Array of Points. Point(xc,yc,zc) is the middle point of an edge to be filleted (for example in the TurboCAD "Fillet Edges" operation, this point is marked with a blue square). Array of Points defines a set of edges to be filleted.Defines the Fillet radiuses. Fillet radiuses are set by Array function. For a single edge the Array contains pair of values, for multiple edges - multiple pairs of values.Fillet Edges Example: *Array(Point(x1,y1,z1), Point(x2,y2,z2), Point(x3,y3,z3)); //defines 3 edges for filleting* *//Point(x1,y1,z1), Point(x2,y2,z2), Point(x3,y3,z3); – 3 middle points on 3 edges to be filleted* Another Example: *Array(r1, r2)-- //array of radius values for rounding the selected edge. It defines rounding //radiuses for 2 ends of the selected edge.* *//r1 – start radius of fillet* *//r2 – end radius of fillet.* Example of Filleting 1 Edge: *G3Fillet(PartA,Point(xc,yc,zc), Array(r1, r2)); //where Point(xc,yc,zc) - middle of the edge.* Another Example: *Door= G3Fillet(Door0, Point(0, -1, (Height-FHeight-4-3/4)/2), Array(1, 1));* *For example (fillet of 1 edge of the box):* *x = Parameter("size", 5, LINEAR, GreaterThan(0));* *r1 = Parameter("r1", 1, LINEAR, GreaterThan(0));* *b0 = Box(0, 0, 0, x, x, x);* *b1 = G3Fillet(b0, Point(x/2, 0, 0), Array(r1, r1*2));* *Output(b1);* Example of Filleting 4 Edges of a Box: *L = Parameter("Length", 5, LINEAR);* *W = Parameter("Width", 3, LINEAR);* *H = Parameter("Height", 1, LINEAR);* *R = Parameter("Radius",0.5);* *g0 = Box(0,0,0,L,W,H);* *g1 = G3Fillet(g0, Array(Point(L/2, 0, 0), Point(0, W/2, 0),* *Point(L/2, W, 0), Point(L, W/2, 0)),* *Array(R, R, R, R, R, R, R, R));* *Output(g1);*Chamfer EdgesThe Chamfer Edges function allows chamfering any edge or multiple edges of 3D object. Format: *G3Chamfer(, , );Defines the 3D object whose edges are to be chamferedDefines the edge or multiple edges, which are to be filleted. Each edge is defined by Point(xc,yc,zc) or Array of Points. Point(xc,yc,zc) is the middle point of an edge to be filleted (for example in the TurboCAD "ChamferEdges" operation, this point is marked with a blue square). Array of Points defines a set of edges to be chamfered.Defines the Chamfer distances. These are set by Array function. For a single edge the Array contains a pair of distance values, for multiple edges - multiple pairs of distance values.A Chamfer Example: *Array(d1, d2)-- //array of 2 offset values at the ends of an edge.* Another Example: *Door= G3Chamfer(Door0, Point(0, -1, (Height-FHeight-4-3/4)/2), Array(1, 1));* *//Here Door0 -is the object whose edge is to be chamfered.* *//Point(0, -1, (Height-FHeight-4-3/4)/2) – indicates this edge.* *//Array(1, 1) sets 2 chamfer distances* Another Example: *x = Parameter("size", 5, LINEAR, GreaterThan(0));* *r1 = Parameter("r1", 1, LINEAR, GreaterThan(0));* *b0 = Box(0, 0, 0, x, x, x);* *b2 = G3Chamfer(b0, Point(x/2, x, x), Array(r1, r1+r1));* *Output(b2);*G3OffsetThe G3Offset function extends a solid face inward or outward. Format: *G3Offset(, , );Defines the 3D object whose edges are to be extendedDefines the face, which is to be extended. The Face is defined by a Point(x,y,z) belonging to this faceDefines the offset distance. A positive value will offset the face outward, and a negative value will offset inwardOffset Example: *G3Offset(PartA, Point(xf, yf, zf), dist);* *Where:* *PartA — is the 3D object whose faces are to be offset* *Point(xf, yf, zf) — is a point for selecting the face to be offset* *dist — is the value of face offset* Another Example: *x = Parameter("size", 5, LINEAR, GreaterThan(0));* *r1 = Parameter("r1", 1, LINEAR, GreaterThan(0));* *b0 = Box(0, 0, 0, x, x, x);* *b3 = G3Offset(b0, Point(x,x/2,x/2), r1/2);* *Output(b3);*G3ShellThe G3Shell function allows shelling the shape of solid object, leaving the selected face open. It creates a shell of a specified thickness from a single solid object. The new faces are created by offsetting existing faces inside or outside. Format: *G3Shell(, , );Defines the 3D object whose edges are to be shelledDefines the face that should remain open. It is defined by the Point(xc,yc,zc) function which describes a point belonging to this faceDefines the shell thickness. A positive value creates an outward shell, and a negative value creates an inward shellShell Example: *G3Shell(PartA, Point(xf, yf, zf), thickn);* *Where:* *Part3 — selects the object which is to be shelled* *Point(xf, yf, zf) — is the point on the face, which should remain open* *thickn — is the shell thickness* Another Example: *L = Parameter("Length", 5, LINEAR);* *W = Parameter("Width", 3, LINEAR);* *H = Parameter("Height", 1, LINEAR);* *T = Parameter("Thickness", 0.2, LINEAR);* *g0 = Box(0,0,0,L,W,H);* *g1 = G3Shell(g0, Point(L/2, W/2, H), T);* *Output(g1);* *//After inserting a shelled object in the drawing, shell thickness can be edited in the Selection Info palette (as well as Length, Width and Height parameters)*G3BendThe G3Bend function is used for bending 3D objects. Format: *G3Bend(, , , , );Defines the 3D object which is to be bentDefines a line about which the solid object will be bent. It is defined by 2 Points: Point(x1, y1, z1), Point(x2, y2, z2). The line must lie on the solid face selected for bending.Defines the bending angle. The angle is measured from the plane of the bent face.Defines the bending radiusDefines the Neutral Depth to set the distance into the depth of material along which there will be no tension or compressionBend Example: *G3Bend(Part3, Point(x1, y1, z1), Point(x2, y2, z2), Angle, R, 0);* Another Example: *P1=Thickness(Rectangle(10,20),3);* *B0 = G3Bend(P1, Point(3, 3, 0),* *Point(3,8,0), 90, 2, 0);* *Output(B0);*Setting and Changing Object PropertiesThe SetProperties function is used to set the properties of objects. Format: *SetProperties(, = PropertyValue, = PropertyValue, ...);Defines the object to be used as the base for the new object with set propertiesDefines the name of the property to be set. The name should be surrounded with quotation marksDefines the value to be assigned to the propertyExample of SetProperties: *BlueRect=Rectangle(10,5);* *RedRect = SetProperties(BlueRect, "PenColor" = 0xff, "PenWidth" = 0.2);* *Output(RedRect);* Another Example: *Side2M = SetProperties(Side2, "Material" = "Wood\Pine", "PenColor" = 0xff);* Another Example: *PL1 = SetProperties(PL0, "Brush" = "SOLID");* Another Example: *SetPlastic = ("Material" = "Plastics\Plain white");* *BoxMaterial = SetProperties(MyBox,SetPlastic);* In the Parametric Part manager there is a special tool to choose the required value for such properties as Material, Pen Color and Brush Style. To activate it, right-click on the property name. This will open the Local Menu either for Material table or PenColor table or BrushStyle table. The appropriate table will appear where the desired value can be chosen.Nesting FunctionsFunctions can be nested within a single expression to optimize scripting efficiency. For Example: *BF = BooleanSubtract(B1,Move(RotateZ(RotateY(Box(-5,-5,-5,5,5,5),45),45),-1,-1,-1));* Example Used in a Small Script: *B1 = Box(0,0,0,10,10,10);* *BF = BooleanSubtract(B1,Move(RotateZ(RotateY(Box(-5,-5,-5,5,5,5),45),45),-1,-1,-1));* *Output(BF*);Functions for Creating TextTextThe Text function defines the text string itself and its characteristics, including fonts, style, effects, etc. Acceptable font values are dependent upon those installed on your machine. Format: *Text(, , );*Defines the text string. Text string can be specified either directly here (with quotation marks) or via an identifier of text objectDefines the text fontDefines the text styleExample: *bsb = Text("BS(b)", Tfont, Tstyle);*TextFontThe TextFont function sets the text font, size, and the angle of text line location. Format: *TextFont(, , , );*Defines the mode of the text: Standard (when mode=0) or Scalable (when mode=1 or any other value different from 0)Defines the text font sizeDefines the angle of text lineDefines the text fontExample: *Tfont = TextFont(0,2, 45, "Arial");* Where: 0 — means that text is Standard 2 — text height 45 — text line is located at 45 degrees Arial — fontTextStyleThe TextStyle function sets the text style including justification, text effects and styles. Format: *TextStyle();*Defines the text characteristics separated with commas. The following values of characteristics are allowed: For Justification: LEFT, CENTER, RIGHT, TOP, MIDDLE, BASELINE, BOTTOM For Text Effects: BOX, UNDERLINE, STRIKETHROUGH, AllCAPS For Style: BOLD, ITALICExample: *Tstyle = TextStyle(LEFT, TOP, UNDERLINE);* Another Example: *//Standard text of Times New Roman font with 5in of font size,* *//with Left,Top justification, with TextBox effect, Bold, Italic, at 45 degrees of Angle* *ht=5;* *font_name = "Times New Roman";* *Tfont = TextFont(0, ht, 45, font_name);* *Tstyle = TextStyle(LEFT, TOP, BOX,BOLD, ITALIC);* *bsb = Text("BS(b)", Tfont, Tstyle);* *Output(bsb);*Auxiliary FunctionsExtentsThe ExtentsX1, ExtentsX2, ExtentsY1, ExtentsY2, ExtentsZ1 and ExtentsZ2 functions are used to calculate the extents of graphic objects. Format: *ExtentsX1(); *ExtentsX2(); *ExtentsY1(); *ExtentsY2(); *ExtentsZ1(); *ExtentsZ2();Defines the object to be usedThe presence of X, Y or Z characters in the function name determines axis along which the extents will be calculated. 1 or 2 index--indicates whether minimum or maximum value should be calculated. Example of Extents: *xmin = ExtentsX1(PartA);* *xmax = ExtentsX2(PartA);* *ymin = ExtentsY1(PartA);* *ymax = ExtentsY2(PartA);* *zmin = ExtentsZ1(PartA);* *zmax = ExtentsZ2(PartA);* *P1 = Box(xmin, ymin, zmin, xmax, ymax, zmax);* Another Example of Extents: *A0=Thickness(Rectangle(H-3/4,D), 3/4);* *A1=RotateY(A0,90);* *xmin = ExtentsX1(A1);* *xmax = ExtentsX2(A1);* *ymin = ExtentsY1(A1);* *ymax = ExtentsY2(A1);* *zmin = ExtentsZ1(A1);* *zmax = ExtentsZ2(A1);* *P1 = Box(xmin, ymin, zmin, xmax, ymin+3, zmin+4);*ParameterPointThe ParameterPoint function defines a parametric point with number and coordinates. Format: *ParameterPoint (,,,);*Defines the number of the parametric point,,Defines the coordinates of parametric pointExample of ParameterPoint: *P0 = ParameterPoint(0, l, -l, 0);* *P1 = ParameterPoint(1, 0, 0, 0);*PointX, PointY, PointZ functionsThe PointX, PointY, PointZ are used to calculate the coordinates of parametrical point. The PointX function calculates X-coordinate of parametrical point. The PointY function calculates Y-coordinate of parametrical point. The PointZ function calculates Z-coordinate of parametrical point. Format: *PointX ();* *PointY();.* *PointZ();*Defines the parametrical point from which the X or Y or Z coordinate will be extractedExamples of Point: *x0 = PointX(P0); // x0=1 for P0 = ParameterPoint(0, l, -l, 0);* *y1 = PointY(P1); //y1=0 for P1 = ParameterPoint(1, 0, 0, 0);* *z1 = PointZ(P1); //z1=0 for P1 = ParameterPoint(1, 0, 0);*Special functions and operatorsIFThe IF function allows various actions to be performed depending upon whether the specified condition is fulfilled or not fulfilled. It plays the role of a conditional operator, and can be used to create branches in the logic of building a parametric part. Format: *IF(, , );*Defines the condition under test using the following comparison operations: == (equal) < (less than) > (greater than) <= (not greater than) >= (not less than)Defines the value of the IF function when the value of is TRUE;Defines the value of the IF function when the value of is FALSE;IF Example: *A = IF(L >= H, Rectangle(L, H), Rectangle(H, L));* *//Regardless of the specified size of L and H, the created rectangle A will be positioned //horizontally (the longer side will be along the X axis).* */* In this example "Rectangle(L, H)" is the TRUE result and "Rectangle(H, L" is the FALSE result. */* Another Example: *Tstyle = IF(dir > 0, TextStyle(MIDDLE, RIGHT), TextStyle(MIDDLE, LEFT));* *//Regardless of the specified size of dir, Text Style will be specified with Right or Left justification*.UNITSThe UNITS function defines the units that will be used in the script. It defines the System, Space Units and Scale of dimensions used while creating objects. This function allows loading parts correctly in drawings with different specified units. Format: *Units([]);*Defines object scaleDefines the units in the English or Metric systemsUnits (1[in]) — this means that the main units of measurement are inches. It is possible to use other units for some particular values even when the entire drawing is created with the default unit. In order to use millimeters for particular values while inches are default units, you can explicity declare the desired unit for these values. For Example: *Units(1[in]);// means that default unit of drawing is inches* *Units(1[mm]);// means that default unit of drawing is millimeters* For example, you can use value M=5[mm]; and Units(1[in]) in the same script. It means that only M value is measured in mm while all others are measured in inches. Moreover, this function allows for scaling the created objects down (when N<1) or up (when N>1). For Example: *Units(2[in]);//created object is scaled up 2 times compared with the case of Units(1[in]);* *Units(0.5[in]);// created object is scaled ½ as large as compared with the case of Units(1[in]);*RefPointThe RefPoint function sets the location of the Reference Point for the parametric part. When the Reference Point is one of the output values of a script, it is inserted in the drawing along with the part. This enables precise insertion of the parametric object into the drawing. Format: *RefPoint();*Defines the (x,y,z) coordinates for location of Reference PointFor Example: *xArrow = PointX(P0);* *yArrow = PointY(P0);* *rf = RefPoint(xArrow, yArrow, 0); //-> RefPoint is placed on the point (xArrow,yArrow, 0)* *Output(rf);*Input and OutputThe Input and Output functions are used for inputting initial values or objects into the script and outputting result objects from the script. Format: Input(); Output();Defines the list of variables or objects for input or a list of results for outputFor Example: *Input(H, W, D, A, Dis);* *Output(SideA_L,Bottom_B,Back_I, Face1, FalseD1, E1,E2,E3,E4, N1, T1, Door, FF,* *SideA_R);* Example of the Output with Conditional Output: *Sw = Parameter("Switch", 1, CHECKBOX);* *P1 = Thickness(Rectangle(5,5), 3);* *S1= Thickness(Circle(2.5),4);* *Output(IF(Sw,P1,S1));* *//Here is either cylinder or box inserted on the drawing* *//depending on checkbox Sw value*min and maxThe min and max functions are used for choosing the minimum or maximum values within a set of values. Format: *min();* *max();*Defines the set of numerical values, identifiers of variables or Array of variablesFor Example: *r=min(2,5,1,7,9);//r=1* *R=max(2,5,1,7,9);//R=9* For Example: *A=2; B=5; C=1; D=7; E=9;* *A1=2; B1=5; C1=1; D1=7; E1=9;* *r=min(A,B,C,D,E);//r=1* *R=max(A1,B1,C1,D1,E1);//R=9* Example of using Array of Values: *A=2; B=5; C=1; D=7; E=9;* *r=min(Array(A,B,C,D,E));//r=1Note:* A Group of objects cannot be used as argument of these functions, because a Group is a collection of graphic objects, rather than a collection of numbers.ModThe Mod function is used for finding the remainder of the integer division. For example, Mod(5,4) is 1, because 5/4 = 1, with a remainder of 1. Mod(7,4) is 3, because 7/4 = 1, with a remainder of 3. Mod(7,3) = 1, because 7/3 = 2, remainder 1. *Note: The Mod function is often used to determine if a number is odd or even, because Mod(AnyOddNumber, 2) = 1, while Mod(AnyEvenNumber, 2) = 0.* Format: *Mod();*Defines the expression or identifier that represents the dividendDefines the expression or identifier that represents the divisorFor Example: *A = 7;* *B = 4;* *C = Rectangle(A, Mod(A,B));* *Output(C);*DivThe Div function is used to perform division. Format: *Div(,);*Defines the dividendDefines the divisorFor Example: *A=7;* *B=3;* *result1 = A/B;* *result2 = Div(A, B);* *rect = Rectangle(result1, result2)* *Output(rect);*Additional Math FunctionssqrtCalculates the square root of a specified number *P = sqrt(b);*asinCalculates the arcsine. Returns the angle in radians *P = asin(0.5);*acosCalculates the arcsine. Returns the angle in radians *P = acos(0.5);*ArrayThe Array function defines an array of values, or an array of Points, by directly listing the elements of the array. In other words the Array function collects geometric objects or values into an Array object. Format: *Array()*list of numerical values or geometric objects An *can be represented by either a value, or the of a value, or by a Point(x,y,z) function.For Example: *Array(Point(L/2, 0, 0), Point(0, W/2, 0), Point(L/2, W, 0), Point(L, W/2, 0))* *// It is the array of points defining the edges for G3Fillet.* *Array(R, R, R, R, R, R, R, R)* *//It is the array of radius values for filleting the array of edges.* Another Example: Can *txt = Parameter("text", "Simple text example", TEXT);* *a = Array(TextFont(0,10,"Arial"), TextStyle(CENTER, MIDDLE, ITALIC));* *//Array of 2 items: TextFont and TextStyle)* *s0 = Text(txt, a);* *Output(s0);*GroupThe Group function collects multiple graphic objects into a group and assigns an identifier name to the result. It allows the script to work with multiple objects as if they were a single object. Also a Group can be the output value of a script. Groups of objects can take part in different operations: Move, Rotate, etc. Format: *Group ();*Defines the list of graphic objects, separated with commas. The may be any graphic objectsFor Example: *bse = Group(bse_below, bse_above); //group of 2 graphic objects* *Br2 = Group(Br0, Br1);* For Example: *Bx = Group(Move(BxL, -Dis*1.5), Move(BxR, Dis*1.5));* *ShelfFBx = BooleanSubtract(ShelfF, Bx);* *Output(ShelfFBx, Bx);*Special Functions without ParametersPIThe PI function calculates the value of Pi = 3.14159...#\$A[email protected]ContourDefines a clipping contour for the resulting object. This is used to clip (remove) sections of walls when the object in inserted into a wall. It uses a referenced contour that is defined elsewhere in the script. The referenced contour must be closed. For Example: *contour = Polyline(P10, Arc0(PointX(C1), PointY(C1)), P11,* *Arc0(PointX(C2), PointY(C2)), P12,* *Arc0(PointX(C3), PointY(C3)), P13,* *P03, P00, P10);* *contourZ = RotateX(contour, 90);* *ClipContour = SetProperties(contourZ, "#[email protected]_Contour" = 1,"PenColor"= 0x0000ff);* *TS = RefPoint (W/2, 0, -elevation);* *Output(ClipContour, TS);*Creating custom functionsWhen scripts of the same type are created, which describe a particular class of parametric parts, it can be convenient to have the sequence of repeated actions as a separate specialized function. To achieve this, the repeated actions can be put into a separate .ppm file. In this case, all input variables should be listed in the Input operator: Format: *Input();* For Example: *Input(x0,y0,z0,x1,y1,z1);* The Output operator should also be defined. Format: *Output();* A custom function created in this manner must be placed in a Macro folder, which is always located inside the folder of the calling script. When the custom function is used, the script's file name (without the .ppm extension) is used just as if it was a built-in function. Format: *()* Below is an example of a custom function. The file box.ppm can be found in the PPM Documentation Samples/Macro folder: *// box.ppm – defines a custom Box function.* *// The custom function is called in this way:* *// B = Box(Xmin, Ymin, Zmin, Xmax, Ymax, Zmax);* *// The function creates a 3D box with given min/max values* *Input(x0,y0,z0,x1,y1,z1);* *R = Rectangle(x1-x0, y1-y0, // Rectangle with Xmin = x0, Xmax= x1* *(x0+x1)/2, (y0+y1)/2); // Ymin = y0, Ymax = y1* *T = Thickness(R, z1-z0); // depth = Zmax - Zmin* *Output(Move(T, 0, 0, z0)); // move result along z to Zmin* *The script below is box* blend.ppm, which calls the custom function box.ppm *//box_blend.ppm uses the custom Box.ppm function in the Macro folder.* *x = Parameter("size", 5, LINEAR, GreaterThan(0));* *r1 = Parameter("r1", 0.5, LINEAR, GreaterThan(0));* *b0 = Box(0, 0, 0, x, x, x);* *b1 = G3Fillet(b0, Point(x/2, 0, 0), Array(r1, r1*2));* *Output(b1);* File location is crucial when using parametric scripts as custom functions. In the example above, if blend_box.ppm lies in the folder D:/Symbols, then it can only find the box.ppm script if box.ppm is located in the folder D:/Symbols/Macro.Parametric Parts Reserved Word ListPILINEARTEXTANGULARMATERIALFONTCOLORCHECKBOXITALICBOLDUNDERLINEBOXALLCAPSSTRICKETHROUGHTOPMIDDLEBOTTOMBASELINELEFTCENTERRIGHTCallArray+-*DivMod/-sincostanatanminmax===!=<><=>=&SolidExtrudeUNIQUEGraphicIdVertexIdVertexFaceEdgeSourceBoundIntersectOperationListBlendArgBlendParamBlendTypeBlendRadiusModeBlendSetbackBlendRadiusBlendSmoothBlendRadiusParamBlendOffsetParamBlendFaceEntityBlendFaceEdgeBlendFaceVertexBlendEdgeEdgeBlendEdgeVertexBlendEdgeVertexMainBlendEdgeVertexAuxShellArgShellThicknessShellFaceShellEdgeFaceEditArgTransformScaleXScaleYScaleZShearXYShearXZShearYZRotateXRotateYRotateZTranslateXTranslateYTranslateZPathProfileLateralFaceLateralEdgeCapFaceCapEdgeJointEdgeProfilesHighLightFaceMaterialArgFaceMaterialFaceOffsetArgFaceHoleArgFaceHoleBendIdBendRadiusBendAngleBendNeutralBendFlagBendPositionBendFlangeHeightBendAxialDistanceBendAzimuthAngleBendEdgeStartPositionBendEdgeEndPositionFace2FaceLoftArgFace2FaceLoftAssemblyAxisInputOutputIncludeUnitsStaticSymbolFolderListMacroParametersParameterParameterPointPointXPointYPointZSetIntervalLessThanGreaterThanLessOrEquailGreaterOrEqualCircleRectanglePolylinePointArc0Arc1FilletIFMoveThicknessSweepConeBooleanUnionBooleanSubtractBooleanIntersectG3FilletG3ChamferG3ShellG3OffsetG3SliceG3BendExtentsX1ExtentsX2ExtentsY1ExtentsY2ExtentsZ1ExtentsZ2TextTextFontTextStyleGroupSetPropertiesPatternCopyExample PPM Symbol**_ _ The following code will generate a window. To use the resulting window you must either:Save the script as a .ppm file, and load the folder containing the file into the symbol library, and then drag the symbol onto a wall.Run the PPM script. Select the result, and turn it into a block. Finally drag the block from the block palette onto a wall.3ArchWindow.ppmUnits(1[mm]); H = Parameter("Window Height", 1200, LINEAR, Interval(400, 10000)); W = Parameter("Window Width", 2000, LINEAR, Interval(700, 10000)); Curvature = Parameter("Curvature", 40, LINEAR, Interval(0, 100)); elevation = Parameter("Window Eleveation", 700, LINEAR, Interval(0, 10000)); sash = Parameter("Window Sash", 30, LINEAR, Interval(0, 100)); W1 = W/3.0; P00 = Point(0,0); P10 = Point(0, H); P11 = Point(W1, H); P12 = Point(2*W1, H); P13 = Point(3*W1, H); P03 = Point(3*W1, 0); C1 = Point(0.5*(PointX(P10) + PointX(P11)), 0.5*(PointY(P10) + PointY(P11)) - Curvature); C2 = Point(0.5*(PointX(P11) + PointX(P12)), 0.5*(PointY(P11) + PointY(P12)) - Curvature); C3 = Point(0.5*(PointX(P12) + PointX(P13)), 0.5*(PointY(P12) + PointY(P13)) - Curvature); contour = Polyline(P10, Arc0(PointX(C1), PointY(C1)), P11, Arc0(PointX(C2), PointY(C2)), P12, Arc0(PointX(C3), PointY(C3)), P13, P03, P00, P10); contourZ = RotateX(contour, 90); ClipContour = SetProperties(contourZ, "#[email protected]_Contour" = 1, "PenColor"= 0x0000ff); TS = RefPoint (W/2, 0, -elevation); Output(ClipContour, TS); PL = Point(sash/2, H); PR = Point(W1 - sash/2, H); ArcWind1 = Polyline(Point(sash/2, 0), Point(sash/2, H), Arc0(PointX(C1), PointY(C1)), Point(W1 - sash/2, H), Point(W1 - sash/2, 0), Point(sash/2, 0)); ArcWindz1 = RotateX(ArcWind1, 90); ArcWind2 = Move(ArcWind1, W1, 0, 0); ArcWindz2 = RotateX(ArcWind2, 90); ArcWind3 = Move(ArcWind2, W1, 0, 0); ArcWindz3 = RotateX(ArcWind3, 90); ArcWindz1D = Thickness(ArcWindz1, sash); ArcWindz1Surf = SetProperties(ArcWindz1D, "Solid" = 0); ArcWindz2D = Thickness(ArcWindz2, sash); ArcWindz2Surf = SetProperties(ArcWindz2D, "Solid" = 0); ArcWindz3D = Thickness(ArcWindz3, sash); ArcWindz3Surf = SetProperties(ArcWindz3D, "Solid" = 0); contourZ3D = Thickness(contourZ, sash); contourZ3DSurf = SetProperties(contourZ3D, "Solid" = 0); res1 = BooleanSubtract(contourZ3DSurf, ArcWindz3Surf); res2 = BooleanSubtract(res1, ArcWindz2Surf); res3 = BooleanSubtract(res2, ArcWindz1Surf); Output(res3);PreviousMacro RecorderNextSDKMade with Material for MkDocs****
