Converting CSYS ProFeature to ProSelection

Hello All,

I have a function that create a CSYS from another CSYS. It works fine when I use the command ProSelect and use the ProSelection in the function.

ProError CreateCSYS(ProName name, ProMdl mdl, ProSelection CSYSREF, double tranX, double tranY, double tranZ, double rotX, double rotY, double rotZ) {}

Now, I'm trying to create de CSYS without asking for the selecion prompt from the user.

I'm trying to get the ProFeature of the CSYS and use the command ProFeatureSelectionGet(). But it doesn't work. I tryied many diferent ways and none worked.

How can I get the ProSelection of a CSYS to use in my function without asking it for the user?

I'm using Creo 8.0.10
