duplicate definition of block ignored

[dmcdonough]

I am getting a "duplicate definition of block ignored" message when copying within a drawing.

I understand that this usually has to do with nested blocks, or pasting in a w-block with a duplicate name, but I am getting this message with any object I try to copy.

 

I understand why it would effect blocks inserted from other drawings but why when copying within?

Could be a leader arrow or dimension tick...could be a block within a block...could be lots of things. I wouldnt worry about it unless you are losing information or it is causing problems with your file.
