Trying to import a CorelDraw drawing exported as .dwf file into CorelCAD 2020.5
After import, I explodex the outline because I saw a reference to needing to do that sometimes.
But when I try to extrude it, the entity is found, but I get a "Cannot extrude self-intersecting entities." error.
A slight change to the outline in CorelDraw and export as .dwf and after import, I can explodex and then extrude.
I don't have any idea what the error even means, let alone how to correct it. Any ideas?
