Datum tag for the axis of a cone on angular dimension

Hi all,

 

My R&D department have a request for which I cannot find a solution .

We are in CREO 7.0.2.0 and we want to show it in MBD.

 

We can attach the datum to the surface, but not aligned it to the dimension (as per the following pic)

How can we do it?

The 10° dim is a 3D dimension from the sketch.

 

Thanks

Best Regards

This is the only clear way of defining a datum for the center axis of a cone or similarly a center plane for a wedge according to ISO 5459:2011. This is certainly a functionality one would want to have in Creo. The only way I know of doing it in Creo currently, is placing it on a surface. You can create surface the stretches up to and slightly beyond the angular dim. Then drag the datum feature indicator (or datum feature symbol as it is called in Creo) so that is looks like it is pointing on the angular dim. Then hide the surface. Add a reference to the actual surface of the cone for the datum annotation to make it fully semantic. I don't think this is an acceptable solution but until it is possible to snap the datum feature symbol directly to the angular dim, I don't think there is another solution. I'd be happy if you can prove me wrong. See the attached pics for a wedge. The procedure should be similar for a cone.
