Problem importing vector DXF from Inkscape to Sketchup

[acastler]

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?
