Very slick! Good tips!

Excellent advice. But what to do if the value in the 3D code is not -1, 0 but -1, 2? The algorithm shown does not work

Hi @nbeyner, thanks for your comment, you are correct. Depending on the source of the model and how the mesh was defined, you may find different edge codes.

I have made a follow up video, covering the case you mention, with a very similar workflow.

Hope it helps!

This is brilliant! BEST advice! Thanks. Maybe you know a way to make a 2D symbol so that graphic replacements affect it? Is it possible?

Hi @nbeyner, with the previous settings using "project2 3, 270, 3" Graphical overrides will work when using Drafting Fills override: 

To get the projected fills to react to cover fills overrides:  just use the following settings in the project command : 

Thank you! You have model contours on 2D. I have no lines with the described algorithm. Does this depend on the original model or can it be controlled?
