I'd like to simplify my project and reduce processing load by using a single DC source for (each of) logic high and logic low. It would seem a simple thing to create an alias 'send' from each DC source, and paste copies of the alias 'receive' wherever needed. However, I can't seem to paste an alias receive into a different hierarchy board than its associated send. Likewise, if the send is on the main page, I can't paste the recieve into a hierarchy board. Is this by design? I've observed this in both 3.8 and 3.9 beta. I s'pose I could create additional inputs to each hierarchy board that needs these logic levels and keep all the aliases on the main page, but that adds to the clutter... Thoughts? Thanks!
