Constraints Based on Parametric Curves

The following methods are used to create special constraints for parametric curves, splines, and ellipses:

constraint_item GCE_AddPointOnPercent(GCE_system gSys, geom_item curve
                                                     , geom_item pnt[3]
                                                     , double k)

constraint_item GCE_AddPointByMetricPercent(GCE_system gSys, geom_item curve
                                                           , geom_item pnt[3]
                                                           , double k)

constraint_item GCE_AddFixCurvePoint(GCE_system gSys, geom_item curve, geom_item pnt)

constraint_item GCE_AddPointOnParEllipse(GCE_system gSys, geom_item pnt
                                                        , geom_item ellipse
                                                        , double t)
