measurement of ring width

[horsetooth]

Hello everybody,

we have a polygonmodel that is constructed like a ring. We want to measure the width of the ring at several points.
The model is not equally wide at all points.
But the measurement shall be taken so that the shortest distance is taken from one side to the other.

Does anybody has an idea how that can be accomplished?

Hello

What about using 3D or 2D calipers in IMInspect?

Cheers

Hi,

Do you have a particular point along the axis of the ring at which you must take the measurement?  If not, you can simply fit a cylinder primitive to your ring, then compare the polygonal model to the cylinder.  The data point with the most negative error will be the point at which you should place a caliper to measure across.  Alternatively, just fit a minimum cylinder to your polygonal model, which will give you the minimum diameter!
