Fit Circle on a Cone Feature

[[Ja...]]

Hi All,

Measured a diameter (highlighted) in three places as there was found to be a taper. Was told (once part was off machine) to measure as a cone, and output diameter from one 'magenta line' to the other. Basically the extremities of the diameter at either end.

As I had already measured 3 circles, I recalled points as a cone then tried the 'circle on cone' feature, using the 'move nominal position along the axis' button. I expected to see a different diameter as I change the Y value (Part is a shaft and sits on machine along Y axis) but this doesn't seem to be the case. Am I missing something.

Images attached to aid, thank you.

Try using cone calculation instead under constructions. That should give you a live diameter change as you move the depth around.

Wouldn't be better to use intersection with planes?

Cone calculation is made to do exactly what you are trying to do!

Cone calculation construction allows you to select planes and gives the same result as intersection construction.

Thanks - i always forget about this. Anyway you need to know some distance to get it, so it's not a bad advice from me to use planes and intersections if that distance can vary 😕
