I'm trying to measure draft inside of a diameter. I've tried using a cone autofeature but it's giving me a error best fit calc. Using two circles is not working for a constructed cone. Any ideas?
Angles?

Did you try using a learned feature. I'd try that with 3 levels. See what it comes up with. If it is a shallow angle it will probably guess it as a cylinder. Go editoveride guess and choose cone. Then, look at it to make sure it has the vector correct.
Call it a day and worry about it on monday? Only ideas I've got.

Try
Have to use other means  other than CMM...
Taper formula  measure top dia, measure bottom dia, find the length and do trig it will give you per side.
Just my 0.02
I am so outta here!!! Have a good Tday...

Draft Angles
I measure a lot of plastic parts and I find any drafted holes or bosses 1 degree or less are difficult to use auto cone to measure. For this application I would measure top and bottom diameters, assign variables, calculated draft angle, create generic cone and then report draft angle.
