I have imported some drawings from a .dwg into my Rhino file to use as reference. Once I started trying to work with a copied file, I realized I had a problem. Looked at it in the perspective view, and low and behold…it’s a mess. Is there some fast way of making all of the linework flat without using MAKE2D? I would love to simply flatten the lines that are there without making a copy like MAKE2D does.
I am using Rhino 5.3.2 on MacOS 10.13.2
Here is perspective view for illustrative purposes (my drawings are the flat ones):
