Hello guys. I know this is an old topic, I just want to leave my feedback about the two routines. The “psimple v1.7” made by Charles Alan Butle, works like a charm. You can select multiple objects and all of them will lose their extra vertices.
The other routine called “Purge-Pline” made by Gile, also works pretty well, but i could see that sometimes it does not delete some curved vertices (lets say about 10% of the vertices in curved segments).
Thank you for the routines guys.
