Links from Requirements to Library Blocks
If you have a requirement that links to a library block and you drag that library block to
a model, the requirement does not link to the reference block; the requirement links only
to the library block.
For example, consider the situation where you have established linking between a library
block (B1 in the following graphic) and a requirement in both directions.
