Description
The TechDraw 3PtAngleDimension tool adds an angular dimension to a View. The dimension shows the interior angle between three points.
Measuring the angle between three points
Usage
- Select three points. The second point will be the apex of the angle. The geometry may be selected in the 3D view or in the drawing.
- If you have selected geometry in the 3D view: add the correct TechDraw View to the selection by selecting it in the Tree view.
- There are several ways to invoke the tool:
- Press the
Insert 3-Point Angle Dimension button. - Select the TechDraw → Dimensions → Insert 3-Point Angle Dimension option from the menu.
- Press the
- A dimension is added to the View.
- The dimension may be dragged to the desired position.
- If needed, add tolerances as described on this page.
Display 3D measurement
Change properties
To change the properties of a dimension object either double-click 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.
