Hello, I have the Block Description Diagram and the internal Block diagram of a block called "B". Now I realize that I want the block B to be a part of the system called A.
It's easy to create block A in the BDD and make block B a part of it.
I'd like to have an IBD of block A that shows B and also its content as they are shown in the IBD of block B.

In this case I don't really care about keeping the IBD of B, I just want a new diagram showing A, its content B, an the content of B.

I found how to show the "internal structure compartment", and also show all the blocks of "B", but they are from the model, not as drawn in the IDB of B.

If so, I'm not sure how if the implementation is also applicable to IBDs, but Christian Damus will certainly be able to tell you...
