Couple of things in play. Plan files sent to DWG are typically black in CA because the background display is white. Most ACAD users have a black background color. In ACAD, you simply change the layer colors to white and they become visible. Civil and survey CAD drawings are usually in units (1") equals 1'. In CA, we typically work in feet and inches. Simply scale 1/12. In ACAD, I need to Zoom Extents for the CA drawing to be in the viewport. The Version is specific regarding the ACAD program. ACAD can be saved back to previous versions, but cannot work in reverse.
