Rotating an ObjectObjects other than curve, convex, faces, and points can be rotated about a specified origin (to rotate these other objects, put them in a frame and rotate the frame). obj.rotate(angle=pi/4, axis=axis, origin=pos) The rotate function applies a transformation to the specified object (sphere, box, etc.). The transformation is a rotation of angle radians, counterclockwise around the line defined by origin and origin+axis. By default, rotations are around the object's own pos and axis. There are no defaults for the extrusion object, and one must specify all parameters: angle, axis, and origin. There are functions for converting between degrees and radians, where there are 2*pi radians in 360 degrees: radians(360) is equal to 2*pi degrees(2*pi) is equal to 360 Also see the rotation function available for vectors.
