I have this plan I have been working on for a couple of weeks an I opened it today to work on it and now any new walls I add will not cleanup. I can split an existing wall an reconnect it and modify them but any new wall fails to connect to the existing ones. New walls will connect and heal to each other bt not the old walls. I can add blocks as well. Everything is on the same workplane, the cleanup feature is checked. Is there something I am missing? I have spent a lot of hours on this and I do not want to start over. Any ideas?
