got a piping drawing where all the pipes are made from a sweep.  There is no length that I can find for the pipe on the sweep usually defined in context to a plane or surface.  would like to be able to make a custom balloon that will show me how long the sweeps are so that I can show a cut length without having to dimension and hide those dims in the drawing.   We have a custom balloon style that works with routing but not with this modeling method....

Any ideas....
