Angle tool
The Angle tool lets you visualize angles such as the ones below. An
angle can be
drawn anywhere in the image by defining three points (handles) such as shown
for the
red angle below.
To draw an angle:
- Activate the Angle tool;
- Click and hold the left mouse button, and drag to draw the angle.
To modify an angle:
- Activate the Pointer tool;
- Select the angle you wish to modify;
- Click on one of the angle's handles and drag it to a new position while holding the left
mouse button down.

Making measurements
Three points uniquely identify two lines that specify an angle. The angle is
the
Euclidean angle in
the world plane. This angle is meaningless unless the world plane
(reference plane) has been identified with the
Reference plane tool.
By moving one or more of its handles, the
measurements will be automatically updated to accommodate the change(s). The
same is true if the reference plane is changed.
