I can't seem to open DWG file i exported from REVIT after i touched it up in Autocad. I have impression 3. I get through picking all the otpisons and then a error pops up saying it can't be imported but it is an Autocad DWG file. Also i tired saving it as a 2007 DWG and still got nothing. I coul dopen the filel before i touch it up in Autocad but the hatches/fills are pink and view port lines show up.
