Can anyone tell me with which node (perhaps GeniusLoci) it is possible to separate, or better identify a block specifically from the cad link? That is, in the linked file I have several blocks, however I want to identify only one to convert it into a family. But I’m not succeeding, even though the block has the same name as the family, even trying to use layer, when I import the family it positions it in all blocks, with the same name and with others.  
I’m new to dynamo, if you can help me, I really appreciate it!
