Circle axis to circle axis

Use this function to measure the angle between two circle axes.

Circle axis to edge

Use this function to measure the angle between a circle axis and an edge.

Line to line

Use this function to measure the angle between two intersecting lines.

Line to line (projected)

Use this function to measure the angle between any two lines. You have to define the direction (X (default), Y, Z) of the active coordinate system to define the projection direction. This will project the second line onto the first in that direction, and if they intersect, it will return a result.

Plane to plane

Use this function to measure the angle between two planar faces.

Plane to axis

Use this function to measure the angle between a planar face and one of the active coordinate system axes (X (default), Y, Z)

Three points

Use this function to measure the angle between any of the three given points. The second point is the shared endpoint.
