Hi I have a one drawing from which I can not copy any objects (line, text, block, etc) and paste to THIS drawing or another. But I can copy from diffrent drawing and paste to THIS drawing. I don`t know what`s wrong. Can anybody help? I have Autocad 2004 LT. On Autocad 2002 LT is the same. I tried save as DXF, but problem didn`t disappear.
