Hello,  
I have a rectangular landscape shaped mesh object (2D) and need to redraw the outline in order to create 4 closed connecting vertical meshes (as a 2D-Stand). Which command can generate the outline from the mesh independent from view?

For comparison: when I convert the landscape mesh to a surface, I can use \_Silhouette for the workflow described. Then \_ExtrudeCrv creates the 2D-Stand. However I prefer not to convert the original mesh to a surface, afraid of losing details.

Thanks!

If you need the outline projected flat, try MeshOutline from whichever view direction you want to project. If you need the real edges of the mesh - assuming it’s open - you can simply use DupBorder…

Great, that command works just fine for open meshes.

Thank you very much.
