Example of ‘3D Angle Bisector'

Front/right isometric view:
A 1. Line
B 2. Line
1 Starting point of the angle bisector is the (virtual) point where the two lines forming the angle meet., length = +5
2 Starting point of the angle bisector is the (virtual) point where the two lines forming the angle meet., length = -5
3 Custom angle bisector, length = +5
