Bypass means direction change to a route. Bypass creation involves ducts and elbows. The bypass components created will have end types inherited from parent duct. The obstructing elements could be any building object including mechanical ducts/pipes, structural column, beams etc., or even the MicroStation solid. The obstructing elements could be part of reference file.
