Recently we had a case escalated to us from our customer from Brazil. Beside few things that went wrong with his drawing he was also getting “The objects in this drawing are approaching the size limit…” message. What they tried to do is very common scenario. In their office they use multiple versions of Civil 3D and wanted to save the drawing created by Civil 3D 2011 to an older file format to be used with Civil 3D 2009. As I said, pretty common request from Civil 3D. But there are few things you should be aware of. See them after the jump.
