Copy -> Paste problem - Help

[AutoCAD Slave]

I have a drawing and when i select certain sections of it then paste onto another drawing sections of it are missing. This even happens if i paste back onto the origonal drawin also.

None of the layers are frozen or anything, why is this happening and how can i stop it.

Help appreciated.

Rich.

**Update** something to do with missing proxy information.

Is there any way around this????

Maybe this drawing was made in ARFACAD(VIKS), ARKO, RoboCAD, or Architectural DeskTop and it has some blocks from that programs. You can try command "WBLOCK". Or, if you know in what program the file where made - try to use there something like export in CAD.

If nothing of this works you may send this file into my male - I'll try to do something... (My male is walk@front.ru)
