A Turning Axis is the axis of revolution for axis-symmetric geometry, which could be manufactured by turning processes. A part may have more than one turning axis. See the section "Turning Axes" in the aPriori Cost Model Guide for more information on turning axes, including system-created and user-defined turning axes.

In the Geometric Cost Drivers pane, expand the Component node (click on the + icon), then click the Turning Axes node. All turning axes for the part will be displayed.

To display individual turning axes, you can click on each distinct turning axis listed under the Turning Axes node.
