Simplify curves for OpenNest and transform guid

I’m trying use OpenNest to nest parts for NC cut boats. The closed curves have lots of relatively small features that can be ignored for the nesting. Use of conves hull is inappropriate for the shapes, so I;ve come up with a solution the works well for what I need and is fast enough.

The nesting of the complified curves works well, however, when I transpose the original guids, it fails to work.

How do I fix this? (29.6 KB)
