[v8i C#] Copy Fence GetContents attachment patterns missing

Hey,

I define a fence, get an enumerator with Fence.GetContents() and use CopyElement(...) to copy all containing elements to a temporary model.

This works fine and as expected UNLESS I try to copy elements that are in an attachment: If I put a fence around an attachment and try to copy the elements then the patterns are not copied. Hatching works fine, but patterns (shared cells) are missing.

Is there something that I have to take care of when dealing with patterns?

Regards

Stephan
