Hello. I need support .if I import one DWG progect (executed with Draftsight 2018 SP2 licensed) within a HVAC tool, the HVAC sw shows a big rectangle (like a big rectangle frame of DWG model, bigger than my dwg project ) within my HVAC sw layout. This big frame is a problem when I use "fit view" commad, because the command fits the frame , not the DWG project, I need. I didn't have these problem with free Draftsight 2018 SP2 versione. What's wrong. May be wrong settng?
