I have been seeing this type of problem fairly often now that I've been building more technic sets. When using angles, parts don't line up the way they should. Has anyone else experienced this? Is this a LDraw problem or Bricksmith? I haven't had a chance to test this with windows software. See pictures from 42021 (Snowmobile) below.
and the official instructions
any thoughts? File Download (this is a partial of the model)
