I imported a DWG into sketchup using the Simlab plugin but I am unable to edit the drawing. (btw, I'm quite new using cad software). The drawing appears to import as a single entity and if I try to select any part of the drawing the entire drawing is selected. The original drawing was exported from Draftsight with a 2013 dwg format. Anyone have any ideas? It is a complicated 2d drawing and I am trying to save a little time here. I need to get it into sketchucam.
