I am having troubles attaching files to the existing .dwg file. I am trying to attach 6 drawings to one file, but evrytime i do it, it gives me a drawing id not valid error. I am not sure how to fix it. It would be great if someone can help me ASAP.
I think Bill want you to check if they are the same release of Civil 3D.

I would try attaching one file at a time. Use the recover command to open the file that produces the error again.

Runtime Error!
