Dimension

There are eleven tools for creating dimensions. From left to right, these tools are:

• Smart Dimension
• Horizontal
• Vertical
• Parallel
• Ordinate
• Radial and Diametrical
• Angular
• Center Mark
• Balloon & Callout
• Length Along Curve

The Smart Dimension tool creates an associative link between the dimension and any referenced curve. This means that modifying the curve will automatically update the smart dimension. The other dimension tools do not preserve a relationship between geometry and the dimension.

Dimension Text

You can specify the dimension text or use the # symbol to automatically fill the field based on the measured value. The text is controlled on the Prompt window.

Dimension properties, such as format, orientation, and more, are controlled on the Inspector.

Smart Dimension

The Smart Dimension tool creates horizontal, vertical, parallel, radial or diameter dimensions based the object type selected and where you move your mouse. Dimensions created with this tool are associative to the curves referenced. Modifying the shape of the curve will automatically update the dimension.

Using the Smart Dimension tool (Example 1--HVP Dimension)

1. Position the cursor over a line such that the Snap tool says “on”. Click the mouse.
2. Move the cursor to place a horizontal, vertical or parallel dimension.
3. Click at desired location to accept the final dimension.

Using the Smart Dimension tool (Example 2--Diameter Dimension)

1. Position the cursor over a circle such that the Snap tool says “on”. Click the mouse.
2. Move the cursor to place a diameter dimension.
3. Click at desired location to accept the final dimension.

Using the Smart Dimension tool (Example 3--Point/Point Dimension)

1. Position the cursor over an object such that the Snap tool says “endpoint”, “midpoint”, “vertex” or “center”. Click the mouse to specify the dimension start point.
2. Position the cursor over an object such that the Snap tool says “endpoint”, “midpoint”, “vertex” or “center”. Click the mouse to specify the dimension endpoint.
3. Move the cursor to place a horizontal, vertical or parallel dimension.
4. Click at desired location to create dimension.

Using the Smart Dimension tool (Example 4--Angular Dimension)

1. Position the cursor over a line such that the Snap tool says “on”. Hold the Shift key and click the mouse.
2. While still holding the Shift key, position the cursor over a second line such that the Snap tool says “on”. Click the mouse.
3. Release the Shift key.
4. Move and click at desired location to accept the angular dimension.

Using the Smart Dimension tool (Example 5--Minimum Distance Curve/Curve)

1. Hold the Shift key, and position the cursor over an object such that the Snap tool says “on”. Click the mouse.
2. Position the cursor over a second object such that the Snap tool says “on”. Click the mouse.
3. Move and click at desired location to accept the minimum distance dimension.
4. This creates a minimum distance between two curves.

Using the Smart Dimension tool (Example 6--Minimum Distance Curve/Pt)

1. Hold the Shift key, and position the cursor over an object such that the Snap tool says “on”. Click the mouse.
2. Position the cursor over a second object such that the Snap tool says “endpoint”, “midpoint” or

“center”. Click the mouse.

1. Move and click at desired location to accept the minimum distance dimension.

2. 

This creates a minimum distance dimension between a curve and a point on another curve.

Horizontal Dimensions

A Horizontal Dimension creates a dimension with horizontal leader lines and vertical extension lines. Horizontal and vertical for the drawing are defined by the x and y axis of the construction plane. To create a horizontal dimension, select the object you desire to dimension and locate the position corresponding to the lower right text location. Modifying the object will automatically regenerate the dimension.

There are three types of horizontal dimensions available, from the sub-tool palette:

Horizontal Dimension tool

This tool creates a single horizontal dimension, from a specified start point to a specified endpoint. Using the Horizontal Dimension tool

1. Click the mouse for the dimension start.

2. Click the mouse for the dimension end.

Horizontal Baseline tool

This tool creates a horizontal series of dimensions with one baseline dimension of the entire distance. Using the Horizontal Baseline tool

1. Click the mouse for the dimension start.

2. Click to set a series of horizontal dimensions.

3. 

Click the mouse for the dimension end.

Horizontal Chain tool

This tool creates a horizontal series of individual dimensions over a specified distance. Using the Horizontal Chain tool

1. Click the mouse for the dimension start.

2. Click the mouse for the dimension end.

3. Continue to define individual dimensions along a surface.

Vertical Dimensions

A Vertical Dimension creates a dimension with vertical leader lines and horizontal extension lines.

Horizontal and vertical for the drawing are defined by the x and y axis of the construction plane.

There are three types of vertical dimensions available, from the sub-tool palette:

Vertical Dimension tool

This tool creates a single vertical dimension, from a specified start point to a specified endpoint. Using the Vertical Dimension tool

1. Click the mouse for the dimension start.
2. Click the mouse for the dimension end.

Vertical Baseline tool

This tool creates a vertical series of dimensions with one baseline dimension of the entire distance. Using the Vertical Baseline tool

1. Click the mouse for the dimension start.
2. Click to set a series of vertical dimensions.

Click the mouse for the dimension end.

Vertical Chain tool

This tool creates a vertical series of individual dimensions over a specified distance.
