Does anyone know if there is a way to create a macro that would give me the minimum cross-sectional area of a part?  This could be useful for quickly finding minimum tensile areas, maximum flow areas, etc...

I've never created a macro from scratch so I'm a little lost on this one.

When I visualize the problem, I see taking a series of planes (maybe .010" apart) and cutting through the part/assembly, from one end to the other, measuring the area at each cut.  The plane that cuts through the least amount of material is highlighted/identified in some way and the resulting cross-sectional area is the output.
