How to evaluate diameter of circle on 3D mesh?

[[ph...]]

Hey all,

I have a mug that has a curved inner liner. I'm trying to measure the diameter ~3.85mm from the lip. I have the parting line created in the STEP file and I can select that as a circle but once I choose "Fitting Element" as measurement principle, I get an error saying "The boundary does not match the shape of the nominal element. (The selected points do not result in a circle)".

How can I choose this parting line on my CAD model, and evaluate the diameter at this location on my 3D mesh? Help is appreciated. 

Thanks,

David

Hello there

If you know the correct distance of the top of the cup to the line that you created on CAD you could create a section that will give you two circles (inner and out circle) and then you could easily measure the Ø of the cup

Hello phphung,

as Diogo suggested, you need to create a section at this position first. Then click the circle onto the section or create a fitting circle from the point selection of the section.
