We’ve added a CAD View to work with CAD files directly. Open any CAD file (DWG, DGN, DXF), select just the entities or layers you want and send them to the Drawing View to use in TPC. Or send parts of your drawing over to the CAD file you have open. Or write a DWG file from TPC, then open it in the CAD View and tweak the drawing before sending it out.
TPC isn’t a CAD program. We’re the No CAD Zone. We don’t want to force you to do your survey drafting in CAD when our Drawing View is so powerful and intuitive. But we understand that you still need to work with CAD. So what is best way to interface with CAD? You’ll find out in the CAD View.
