Select the tapered face of the hammer head shown, and on the
feature selector, click Intersect Circle
.

DimXpert recognizes the truncated cone as a manufacturing
feature. In this exercise, you find the diameter of the smaller circle using an
intersect circle.
DimXpert recognizes an intersect circle as the only possible
intersection with a size dimension and a tapered face, which provides the circle
diameter.
Intersection geometries with location dimensions allow
easy dimensioning of drafted or regular shapes. Intersection geometries with
size dimensions allow easy dimensioning of radial features.
When you use intersection geometries, you choose the type of
geometry and two planes. DimXpert creates a new feature where the planes
intersect for dimensioning purposes. This is denoted with a blue dashed
line.
