Inconsistent wall thickness

[[Ja...]]

Looking for ideas on how to attack this. Imagine a short piece of pipe. The OD is a rough sand cast surface. The ID is a smooth bore. I need to find where the thinnest part of the wall is, and what the thickness is at that point. The locations of the ID and OD are not consistent and will move from one part to the next so both size and form will vary quite a bit. Location and size of the OD is irrelevant, only the thinnest part of the wall is. So even if there is significant form distortion in one area of the OD, that still may not be where the thinnest part of the wall is. Single pointing is not an option, and mechanical filtering will be kept to a minimum.

Curve to Curve is most likely your best bet.

I've never done that before. After I make the 2 curves, what would I do?

Size - Curve Dimensions - Curve Distance.

Select one of the Curves as the Inner Curve, and one as the Outer Curve.

You can report the Average, Max, or Min. It will also show you on the CAD display where the max/min is.

Wow. That's too easy! Thanks!
