TechDraw DiameterDimension/en

Description
The Dimension Diameter tool adds a diameter dimension to a View. The dimension may be applied to any circular in the drawing. The distance will initially be the projected distance (ie as shown on the drawing), but this may be changed to the actual 3D distance using the tool.



Usage

 * 1) Select a circular edge in the drawing. (Note some arcs which appear to be circular are actually ellipses or BSplines. You cannot make a diameter dimension in these cases)
 * 2) Press the  button
 * 3) A dimension will be added to the View. The dimension may be dragged to the desired position.
 * 4) If needed, add tolerances as described in this page.

To change the dimension properties either double-clicking onto it in the drawing or double-click on the dimension object in the model tree. This will open the dimension dialog.

Limitations
Dimension objects are vulnerable to "topological naming" issues. See the information in the TechDraw Dimension Length tool for more information.
