Can I re-create the coordinate system using the coordinate system generated by ProFeatureCreate?

[CHASEONHO]

I created a csys_feature using ProFeatureCreate.

Use ProFeatureSelectionGet to get the ProSelection handle of the created feature.

I tried the following values for PRO_E_CSYS_ORIGIN_CONSTR_REF among the options of ProFeatureCreate.
value_data.type = PRO_VALUE_TYPE_SELECTION;
value_data.v.r = ProSelection handle of feature created using ProFeatureSelectionGet

The coordinate system is not created and displays the Coordinate System dialog box.
The following text is displayed in the text area below.
>>Select up to 3 references, such as plane, edge, coordinate system, or point to place coordinate system.

Is there something I missed?

Does the ProSelection handle of PRO_E_CSYS_ORIGIN_CONSTR_REF unconditionally use the handle obtained from ProSelect?

This has been resolved.
Now I need to automatically replace the selection to generate the pattern.
We use the toolkit API to generate directional patterns.
Refer to csys_axis after obtaining it through ProSelect.

If I refer to the Z direction of the coordinate system feature created by the toolkit API, is it possible without ProSelect?
How do I try it?

Thank you.

Just for my curiosity about API ProFeatureSelectionGet. Were you working for part only or assembly?

For your query, get ID of created CSYS. Then use ProModelitemInit() and follow it with ProSelectionAlloc to have allocation of created CSYS.
