Is there a way to make a beam system "rest" on supports that are selected with the "Pick Supports" tool? I have a roof that slopes in 2 directions to the drains. The beams slope like I want them to, and I can make the joists slope using the 3D snap, but this means that I have to draw each joist. I'd love to use a beam system for the joists, but it is flat, or at best linked to a sloped work plane, and this doesn't suit the condition. I hoped that picking the supports would cause the joists to rest on the beams, but no joy.
