TechDraw 3PtAngleDimension/en

Description
The 3-Point Angle Dimension tool adds a angular dimension to a View. The dimension may be specified by selecting three Vertices on a View. Note that the second of the three Vertices is the apex of the angle. The Angle3Pt will initially be the projected angle (ie as shown on the drawing), but this may be changed to the actual 3D distance using the tool.



Usage

 * 1) Select the points or edge which define your measurement.
 * 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 properties of a dimension object either double-clicking it in the drawing or in the Tree view. This will open the dimension dialog.

Limitations
Dimension objects are vulnerable to the "topological naming problem". See TechDraw LengthDimension for more information.
