BSplineSurface to Cylindrical Surface


I want to change a diameter of a cylindrical surface. But when i see the type of the cylindrical face, it is defined as BSplineSurface. How can i change the diameter of the cylindrial surface if it is kept as BSplineSurface?

You first need to convert your BSpline into cylinder (provided that it is a cylinder within some tolerance). This is done by a licensed component - Canonical Recognition - Contact OCC support/sales for a demo.

P.S. What a day ! My 3rd reply in a row today is leading to promoting a licensed commercial add-on of Open CASCADE. Should I ask for promotion fee ;-) ?
