Hello,
Drawing curves in 2D sometimes get 2 or more identical curves stack together.
Is there a way that Moi find and deletes thoses identical curves?
Its a tedious process when manual clicking a lot on every curve to find if there is more the 1 curve.
Browse the forum and didin`t find a similar question.
Thanks
