Hi, again me!
I’m writing again as I’m looking for a better solution.
I have many polysurfaces like this;
I want to shorten these polysurfaces by six millimeters from the left and right.
I have tried many method; (Brep edges> offset curve/ offset surface or discontinuity> offset curve) but i can’t do this. Sorry for my questions, I’m new here&Grass.
