Hello!I'm trying to open or import a DWG line drawing into Rhino, but it gives eighter error or the message that some information e.g. proxy cannot be imported in Rhino. But it is only some lines from an architectural plan - I deleted what I don't need and saved them as a new document.Has someone an idea where the problem might be?

What is an "eighter" error?  Never heard of that.Proxy objects?  What program was used to create the original drawing?
