How to activate a cross section using ProToolKit?

Hi,

I have created a cross-section for a part model using the method "ProXsecPlanarWithoptionsCreate()" in "C(ProtoolKIT)" but it not activated by default.

How do I activate it automatically (Programatically using C(ProToolKit function)) while it is created?

Is there any function/method to activate the cross section in C (ProToolKit)?
