I’m importing a very simple .dxf file (a letter A) after explote 2 times to use it as lines, I push the object to make it 3D, and after that I try ti export that 3D letter to .stl, .odj, collide, etc and dont’t work, no error, no nothing, just doesn’t export, but if I make a 3D square and try to export that, works, this only happens when I try to import an object from Illustrator to Sketch and try it to export as STL
Do you have Export Selection selected in the options? If so, deselect it. there is currently a problem with Export Selection in SU2021.
That make the trick, jajaja impressive to know that was the issue
