### Axial and Radial Options

When creating either a Circular or Total Runout FCF dimension, two options will appear in this area, Axial and Radial. These identify the type of runout. In some cases the input feature or features automatically determine which of these two options is selected:

- Axial - The runout is measured on the end surface of a cylindrical part.

- Radial - The runout is measured on the cylindrical surface of a bore or shaft.

For a Circular Runout with a circle feature as an input, this area also displays a surface type drop down list with two options: Conical and Cylindrical.

Feature Control Frame options area for a Circular Runout with Conical selected from the list and a Nominal half cone angle box

This list defines the surface type for the circle feature. If it's on a cylinder, select Cylindrical. If it's on a cone, select Conical.

If you selected Conical, an additional edit box called Nominal half cone angle appears so you can define what half cone angle to use in the runout calculation. PC-DMIS calculates the runout of a circle measured on the surface of a cone perpendicular to the cone surface. It does this by multiplying the cylindrical result by COS (Half Cone Angle).
