Functions Introduced:

An axis is represented by the object ProAxis, which is declared as an opaque handle. The function ProSolidAxisVisit() visits all the axes in a part or assembly. An axis created explicitly using the Creo Parametric command Model > Axis will be contained in a feature of type PRO_FEAT_DATUM_AXIS, but axes can also exist in features of other types, such as PRO_FEAT_HOLE.

To find the feature that an axis belongs to, describe the axis in terms of a ProGeomitem object using the functions ProAxisIdGet() and ProModelitemInit(), then call ProGeomitemFeatureGet().

You could also traverse axes using the functions ProSolidFeatVisit() and ProFeatureGeomitemVisit(), described in the section Visiting Feature Geometry. As input to ProFeatureGeomitemVisit(), use the type PRO_AXIS. You would have to visit features of any type that could contain axes.

Always remember to use the function ProGeomitemIsInactive() to skip over axes used internally only.

The function ProAxisSurfaceGet() provides the ProSurface object that identifies the surface used to define the axis position.
