Hi gurus,

What I am trying to accomplish is air flow in a duct that must have the same cross sectional area at all points along the duct's centerline, while the cross section shape varies to cope around keep out zones.

So far I am using a cut extrude feature to cut normal to the duct, then a planar surface is made on the hole revealed by the cut. Then use the measure tool to find out the area.

This is tedious and not a way to satisfy the design criteria...at all points the cs area is a single value.

How do you guys think it should be done instead?

Thanks,
KC
