I can get the data of my constructed b-spline surface, like in the VB.net example at http://help.solidworks.com/2011/English/api/sldworksapi/Get_B-Spline_Surface_Parameterization_Data_Example_VBNET.htm

But is it possible to adjust this parameterization data?

Say for example we want to change te value of the controlpoint at row 3 and column 2...

You can get this controlpoint by "controlpoints = swBSurfParam.GetControlPoints(3, 3);", but how do I adjust this value?
