Function Documentation

generate()

def rotation_generator.generate	(		normalVector,
			aMin = -360,
			aMax = 360,
			cMin = -360,
			cMax = 360,
			compound = False
	)

Generates Gcode rotation to align a vector (alignVector) with the positive Z axis.

It first rotates around the Z axis (C rotation)
to align the vector the positive Y axis. Then around the X axis
(A rotation).

The min and max arguments dictate the range of motion allowed rotation in
the respective axis.
Default assumes continuous rotation.

Returns a list of path commands for the shortest valid solution

If compound is False, axis moves will be broken out to individual commands

The normalVector input from a typical face (f) can be obtained like this:

    u, v = f.ParameterRange[:2]
    n = f.normalAt(u,v)
    plm = obj.getGlobalPlacement()
    rot = plm.Rotation
    normalVector = rot.multVec(n

relAngle()

def rotation_generator.relAngle	(		vec,
			ref
	)

Takes a vector and a reference axis (refAxis) vector. Calculates the
relative angle.  The result is returned in degrees (plus or minus)
