Been away from Visio for a couple of years so please forgive such a simple question. I can't remember how separate lines. Example, using line tool I draw a simple rectangle. The corners join and from then on it acts as an object. Now I want to remove one line so I can make it a five sided object, like a house shape. For the life of me I can't rememeber how. I've played with group/ungroup, join/unjoin, snap, glue, etc. Gotta be something simple I'm missing. Any help appreciated. thx
