Depth of a dent on a tube

[[ro...]]

I tried understand the post below about a bulge on a tube, but I think mine should be simpler. Im not an expert by no means so this may be simple for most. I had a tech bring me a tube. He dropped on it and damaged it. He wants to know how deep the dent is in the tube. Im not exactly sure how to give him the deepest point? I scanned it and looked at roundness. Then I thought Im not sure exactly how to give him the deepest point??

I think there is a lot ways to show that. If you are working with a circle, you could use "2 Point Diameter". That will give you the minimum distance and the maximum distance.

I agree with jason, there's a couple different ways.

Min feature
Create a very simple program with a cylinder & a point as your alignment.
make a point where you think the dent is.
in the strategy of the point make a pointset of about a half inch diameter with maybe 15 lines, set step width to be about .002" inch.
then create a min feature and insert the point in, set Z
then maybe compare the Min feature Z to the Z of another point right next to the dent?

Or just look at it on a comparator.
