Wall Joins in VW 2010 in Architecture Posted November 6, 2009 Everyone: I am not aware of any of these problems post-SP1. If you have specific examples, please e-mail me directly with the files and explanations, at email@example.com. I will say this, however - when you are trying to "T-join" at an "L-join", the component joins of the L-join will be removed. This is by design. We are aware that joining components at these three-way intersections is a major wish, and we plan to address it in a future release. But for now, this is the expected behavior.
