TechDraw Dimension Link

Description
The Dimension Link tool creates a link between 3D geometry and 1 or more Dimensions on a Page. This link allows the Dimension to use actual 3D values instead of 2D projected values.

How to use

 * 1) Create your Dimension on the drawing page as usual.
 * 2) Select geometry (ex an Edge) in the 3D model view that corresponds to one of your Dimensions.
 * 3) Press the  button
 * 4) A dialog will open. Select 1 or more Dimensions to be linked to the selected 3D geometry.
 * 5) Press "OK"

Options
None.

Properties

 * 1) The MeasureType property of a linked Dimension will be changed from "Projected" to "True".

Scripting
Dimensions can be linked to 3D geometry using Python.

Limitations

 * 1) Dimension links are very sensitive to the "Topological Naming" problem.  It is recommended that linking Dimensions be one of the last steps in your process.
 * 2) The Link tool will not stop you from making illogical links.
 * 3) There is currently no way to break a link.  You can change the MeasureType back to Projected and the Dimension will use the Projected value instead of the True value.
