The Preferences dialog, accessed from the ViaCAD menu, allows you to customize various start-up and runtime settings for ViaCAD. The Category section lists the available preference groups. The Settings section displays the interface for the selected category. The preference group settings are detailed below:
The colors category assigns the foreground and background color.
Specify the background color of the drawing window.
Specify the foreground color of the drawing window.
Displays the foreground and background into a preview area.
The Display preferences page sets settings for default display resolutions of curves, surfaces, and solids.
The Object Type pull down provides a means to set separate resolution settings for curves, surfaces, and solids.
The Resolution pull down menu provides options for setting the resolution between coarse and sup
The Pen Weights pull down menu provides options for the displayed pen weights that have been customized in the drawing, as they appear when printed.
Printed Line Cap
The Printed Line Cap provides three options that control how line ends are printed. The three options are butt, round, and square. Note, these options are only activated upon printing.
Sets the default settings for the Snap tool. For more detailed information on Snaps settings, see “Snap Settings” on page 3
The pixel radius which is examined for the Snap tool.
The angles that are highlighted when referenced from a wake-up snap.
The angles that are highlighted relative to the first snap point.
Percentage along a curve that is examined for snap locations.
This category sets up the preferences for filing and back up file options.
Save native PICT/BMP only
When this option is selected, images are saved in the native format for either Mac or PC. The native format is more compact, but will not display on both Mac and PC computers.
Clear Undo on Save
Clears the contents of the undo buffer after a save file. Clearing undo buffers frees up considerable memory for additional commands.
Save Display Lists
Saves the display list for surfaces and solids. This includes the vector and facet display lists for each entity. Saving the display will make file loads faster, but file sizes larger.
Read-only network file sharing
With this option enabled, files are locked when read by the application. This prevents others from reading and writing a file you may be working on.
Checking the Save File Previews option will save a preview image of the file. The preview is seen with the File: Open command. File previews are cross platform compatible.
Save Pen/Text Settings with file
Checking the Save Pen/Text settings with file option will save any annotations in the drawing along with the file.
Save Unit Settings with file
Checking the Save Unit settings with file option will save any localized measurement units you have set along with the file.
Automatically saves the current drawing into a file located in the back up folder. Saves up to a user specified maximum. Back up files can be created every so many commands or every so many minutes.
This category assigns general settings including axis, tool tips, short cuts, and dialog positions.
Enable Tool Tips
Displays, in the prompt window, a brief description of an icon as you move your cursor over its tool image.
Enable Short Cut Keys
Turns on or off the ability to use short cuts for quick command access.
Enable Tool Cursors
Turns on or off the ability to use tool cursors. Two types of tool cursors exist which support snapping or selection operations.
Enable Auto Resolve
Immediately resolves dependent geometry when changes are made.
Save Palette Positions
Saves all displayed tool palette positions on the screen when you exit the program.
Show Axis at Start Up
Displays the XYZ axis located at the origin.
Changes the definitions of side and front views to reflect mechanical or aerospace design conventions.
Arrow Key Nudge Distance
The distance used to move objects while in the Select tool using the arrow keys.
This category assigns the default display grid settings.
The dX and dY spacing between major grid lines.
The X Divs and Y Divs (minor grid lines) displayed between the major grid lines.
Displays the grid as dots or lines.
The number of cells in the grid.
The display color for the major grid lines. The minor grid lines are displayed as a different shade of this color.
Display Grid at Startup
Enable this item to display the grid when the program is launched.
Snap to Grid at Startup
Enable this item to activate grid snapping when the program is launched.
The Localization category displays options specific to language localization.
Use Comma as Decimal
Replaces the period used in floating point representations with a comma.
The Select category displays options for picking objects.
Pick Box Size
The pick aperture size for the snap tool and selections.
Enable Ambiguity Popup
Displays a popup menu with all the objects in the pick region. The user then picks the object of interest. If off, the object closest to the view is selected. If the objects are at the same depth, the object that was first created will get selected.
Selected objects Color
Sets color used to indicate a selected object.
Select Fence Mode
Sets the method used for picking with a bounding box. Entire object extents require the user select the complete extents of the object, whereas partial extents require only a portion be fenced to select.
The selection box uses window overlays with transparencies. You can control the selection background color and transparency level with the transparency slider located at the bottom of the Select Fence Mode.
The user can modify the color and transparency level associated with the selection box. To change these attributes, display the Preferences dialog box and pick the Select category. The selection transparency and color are controlled under the Select Fence Mode control grouping.
The Units category displays the options for units of measure used for display of numeric values
The Units pull down sets the unit format for numbers displayed in dialog boxes and Data Entry Windows. At this time, ViaCAD supports six different units of measure. These units and their associated symbols are listed below:
|feet/inches||' "||ft-in||1' 0"|
Display Decimal Digits
Sets the number of digits used to display floating point values in the Data Entry Fields and dialog boxes.
Display Decimal Angles
When checked, this option will display angles as decimal values instead of degrees, minutes, and seconds.
Display Value Units
Use the settings under the Units category to configure the application for working with feet-inches. The data entry window and unit display fields will reflect the current unit settings. When the unit settings are selected as feet-inches, the accuracy menu provides a drop-down list of fractional settings.
The Tool Bar data entry window reflects the preferences for unit settings. When using the feet/inches unit settings, data entry fields will display and process with feet/inches notation.
Feet/Inches Settings in Data Entry Window
All fields including the data entry window and dialog input fields support an intelligent unit parser. At any time, you can type in a value supporting any unit expression. Examples include:
14" + 63cm
Be careful about typing in a minus sign between the feet and inches. This will be interpreted as a subtraction expression.
14'-11" = 157inches
Show Dimension Unit Symbols
When checked, this option displays unit of measure symbols for dimensions in the drawing. When unchecked, unit symbols are not displayed. You can also show/hide unit symbols for individual dimensions by selecting the dimension and enabling the unit symbol using the Inspector.
The User Interface category displays options for controlling dialogs, icon display, and wheel scroll direction.
Dialog Collapse Timing
The Expand and Collapse time sets a delay for how long the cursor must be out or in a dialog to collapse.
Click the Use Small Palette Icons check box to display icons 24 by 21 pixels. The default icons are 30 by 28 pixels.
Wheel Scroll Direction
For those users with a wheel button on their mouse, there is a new option to reverse the direction of the zoom.
Disable 3DConnexion Rotations in Ortho Views
Select to disable 3DConnexion rotations while in Ortho views.
The Audio Prompts check button enables speaking of the message line prompts. This is particularly useful with tasks such as 3D digitizing where reading prompts is difficult.
The Resolution category allows the user to define custom settings for display resolutions.
- Factory Changes all the settings for all preference groups back to the original installation values.
- Revert All Resets all values to the values prior to opening the dialog box.
- Cancel Resets all values and exits dialog box.
- OK Exits and writes out all changes to the preferences file.
Dimension and constraint tools are available to help manage the geometric relationships between 2D shapes.
These relationships are used to remember design intent of 2D sketches, which typically drive 3D solids
User can modify and change colors for over-defined constraints, under-defined constraints, fully-defined constraints and locked constraints from this panel.
This option shows the registration info about the user and product e.g. serial number, node id, powerpack etc.
