We finished the discussion in private e-mail, but for any observers, here was the resolution:
If you float an object up in the air with a positive elevation, then FrameForge allows it to intersect anything. But if you give an object a negative elevation, it intersects with the ground but not other objects. (We were thinking of boats as a case where you'd want that behavior.) The tree branch that Banksyde was trying to intersect with a wall had a negative elevation. The solution was to temporarily turn off collision detection (Tools > Disable Collision Checking), move the branch into place, and re-enable collision detection.
