Angle Measure Tool
The Angle Measure Tool is used to measure the angles between two edges or surfaces.
Go to the Design tab in the top toolbar and choose the "Angle Measure Tool". Now move over to the first vertex or edge. Then, click in the direction where the angle needs to be measured
Note:
1. The dimension and angle measure tool works the exact same way in 3D and 2D.
2. All the measurements made can be moved, edited, hidden, or unhidden as required. To select all measurements together click on the filter selection dropdown & check the “Dimension line” option. You can then hide, unhide or delete these together.
