Radius in Z

Radius in Z

Newish to CMM programming, we have ph20 head and CMM manager 2022 software. So there will be times where I have a radius that needs to be checked. For some reason I struggle to find good ways of checking the part. Like if the radius goes around a lathe part. 3d features won't pick it up and sometimes if there is line following the radius I can use that with a 2D teach, most of the time it just won't recognize what I'm trying to select unfortunately. Is there a good way to do this? In my mind it should almost work like a cone.
