I received a dwg plan from a consultant that I need to use and I want to get the lineweights correct. He sent me their CTB file, which, as I understand it , is the file that maps their colors to pen weights. Is there any way to create a translator that uses the information in the CTB file to convert AutoCad colors to ArchiCad pen weights? I mean, any way other than having him send me a text version of their conversion table that I use to manually create a translator?
