Hello! I have tried everything with importing a vector file DXF exported from Inkscape, but I can t manage to erase the faces (perforated wall), sometimes i can erase a few faces, but most of them I can t erase them. Someone knows the best way to export a vector file from an illustration software like inkscape to sketchup or how to solve this issue?

I had the same problem, i tried everything said here and nothing worked, what i last did was exploding everything and then exporting it to older version of autocad. And now it works.
