Just recently I received a file containing a 3D model extruded from a .dxf 2D file.
I'm trying to replicate that 3d model from the original .dxf file.
I notice that the 3D model has this kind of polygons (concave Ngon), not squares, but a square intervened by another square with no additional diagonal edges.
When I try to create faces\polygons from the 2D file, I get this kind of topology where the face overlaps everything and creates a single square polygon.
How Can I make it behave like the first one above?
