Sketching on a reference plane

Question asked by John Christensen on Sep 28, 2015

What is the correct command to force sketchmanager to recognize planes other than in the xy direction.  The below macro works well when working on  the XY plane, but fails completely to recognize and reorient a sketch to any other plane.  I looked at swRefPlane.Transform as a possible solution, but am not understanding  1) if it is the real solution, 2) how to implement it.



'   1)part is open, close all sketches

'   2)pick on a spline from a sketch

'Post condition:
'   1) reference points are located along curve, evenly distributed

'    2) reference plane is placed coincident with 2d sketch of points, and renamed for future access

'    3) sketch points are located directly over reference points

'    4) currently an issue with sketch orientation working correctly, XY works fine, others do not
