Having some problems with the wall join tool (using Vectorworks 2010). Walls autojoin, but often do not heal correctly. For example, when joining 2 walls with the 'L join mode', the walls join, but a line remains, as if one wall is butting another. This occurs whether walls caps are on or off. Fiddling with the walls sometimes but not always solves the problem: ie pulling the walls back from each other and then re-joining.
Any suggestions?
