Visibility programatically in Inventor

Here is an example of how to set the visibility of a workpoint

       CComPtr<WorkPoint> pWorkPoint = nullptr ;

       GetWorkPointByName (pWorkPoint,csPointName,pPartCompDef) ;

       if (bMakeVisible)) {

           pWorkPoint->put_Visible (VARIANT_TRUE) ;

       } else {

           pWorkPoint->put_Visible (VARIANT_FALSE) ;

       }
