Hi everyone, I have a little struggle to copy/paste elements from a document to another (in this case from a DWG to another DWG). I tried to use the method "CopyEntities" in the target document after getting all the entities from the source document but the method does nothing. It does not even bug.

I tried to use the method "InsertExternalReference" and it worked, but I was told after that this method keeps the reference of the source document, which we do not want here.

How can I solve this case ?

Thank you.
