measure a cone/plane intersection point.

[zbailey]

Ok, so here is whats been kicking my *** the last half of the day. On this print they have a cone with a diameter/tolerance callout. The location they want is the ID of a location that it meets a cavity. Cavity isn't able to be measured as the cone mating end is much larger than the ID of the pass through on the other side. I am currently trying to create a nominal plane at the location and project the cone but it will only project the largest dia. Is there a way to measure the cone, and project the angle of the cone to get a measurement at the plane location? That is essentially what they want but I am struggling to achieve this.

Big thanks in advance for any help. Only got 1.5yr in this stuff, and all of it has been self taught or taught by someone who was self taught so I am ignorant of some functions still to this day.

construct a circle, cone/plane.

You should be able to do a constructed circle at the intersection of a plane and cone. If you need to, use a generic feature plane at a given distance from another surface and use that as your plane feature for constructed circle inputs.

We got it figured out this morning. My apologies for not checking on the post Monday when I got it. Was slammed all day. We are running 2014 (soon to switch to 2019r2) and I couldn't see a way to measure the dia of an intersection of a cone and plane. A more experienced coworker found a solution in the properties of the projected circle that measured the minor dia, so all is well now. Learned something new. When I was trying to project it, it was wanting to take the dia at the middle and project it into the plane. I have only limited experience with 2014 prior to this employer, but I don't recall 2019 or 2017 ever having done that to me.
