Hi everyone, my company and I are having too many issues with the files dwg. we cant copy blocks or anything and paste between files, said that is already defined or doesn't said nothing at all. simply doesn´t pasted. But many block definition was created, for example: *D31880, tens of blocks, and the file become too heavy and slow. Someone can help me to find the reasons or this issues for Autocad 2012. Thanks.
The blocks that started with * either made with other CAD program or were special coded when MINSERT into the drawing (probably with DETER.VLX from Dotsoft.com)
