About Exporting to U3D
You can export Creo models as stand-alone U3D (Universal 3D) graphics or as U3D graphics in a PDF file. However, several Creo features are not supported in an export to U3D:
Assembly cuts
Datum points and datum curves (datum csys axes )
Views of the model in its exploded state
