I have not personally used it, but it appears that it will identify any curves that are not actively being used to drive a feature, and present you with an interface to delete whichever ones you don't want. I can see where that would be useful for someone who modifies curves or uses trial-and-error to program parts and is left with a bunch of extra unused curves...or just for general cleanup at the end of a programming session.
Hi @julior873G4,
When you try to delete unused curves which you cannot find easily and FeatureCAM throws a warning when you select any used curve and if they are multiple, you always have to keep on pressing Ok or Cancel which is quite annoying. This is the reason behind development of this macro 'delete_curves.bas' which displays a list of unused curves with their names. If you say OK, that macro deletes all the unused curves. So you will be remained with used curves only.
I hope I have answered your question. Click on 'Accept as solution' if I answered your question fully or let me know if you have any additional queries.
Thank you.
