How to Rotate a Point About an Axis

The rot function rotates a point about an axis and returns the resulting point.

rot(p,origin,ang)

Rotates point p through angle ang about the Z axis passing through the point origin, as shown in the following example:

rot(p,AxP1,AxP2,ang)

Rotates point p through an angle ang about the axis passing through points AxP1 and AxP2, as shown in the following example. The axis is oriented from the first point to the second point.
