Measuring angle
To measure an angle, toggle on "Specifies angles(clockwise)" or "Specifies angles(counterclockwise)."
For paths that are not closed, the direction from the 2nd segment to the 1st segment determines which angle (clockwise) and angle (counterclockwise) to choose.
For shapes of closed paths, selecting "Specifies angles(clockwise)" always specifies angles outside the shapes, while choosing "Specifies angles(counterclockwise)" will specify angles inside the shapes.
Important: only the angle between two straight lines can be measured. Specees considers any line with handles a curved line. Before measuring the angle, please remove the handles using the "Anchor Point Tool" (Shift+C).
The position buttons will have no effect when measuring angles.
