Unable to open old drawings properly of BricsCAD in newer versions of AutoCAD and BricsCAD
Attached drawing file is giving trouble to insert external drawings properly. I have a customer file(probably older file) consists of 27000+ drawing entities displayed improperly or corrupted one. When I tried to insert a drawing(SOLID) from external ref into the customer supplied .dwg file its showing in a single lines. But the same file inserted in a new drwaing file display correctly without issues. I just want to know the root casue of the issue. I have explored the drawing the file using TrueDWg and ODAMFC APP but still unable to find the root casue.Any help in giving the true casue of this issue is really appreciable. Attached are the required dwg files(minimized versions).
