Error reading surface temp file

Anyone ever get this error in 2020.

This is likely a case of R-22934 / D-41195.  The issue is the handling of the custom WCS.  The issue can happen in legacy surface toolpaths (finish/blend, finish/project, rough/project ...) but not in 3D HST.  The issue has been corrected for Mc2021.

 

For Mc2020, the best work-around is to rotate incrementally the WCS plane.  Rotate it 5 degrees about Z, regenerate the path, rotate it -5 degrees about Z and regenerate the path a 2nd time.  If this works, great.  It doesn't always work.  (I was unable to learn why it does / doesn't work.)

 

The second best work-around is to rotate incrementally the WCS plane 0.000001 degree about Z and leave it rotated.  To do this, you must rotate incrementally, twice, but you don't need to regenerate the path in between steps.  Just apply these two incremental rotations:

This does alter the WCS.  The resulting path motion will be slightly different than what the original WCS would yield.  I see differences of about 0.0003 in the tool positions.

Ok. My coworker was rotating planes and the error came then didn't appear when he rotated back.
