DG Kernel Forum

Hello everybody,
I'm new to this forum. I recently started to use this software in my CAM application. I would like to use it for 2D bspline modeling.

I am clear about using control points, but I also need to reproduce editing a 2d curve via modifying its points. Suppose I have a curve interpolating an array of points. I would like to be able to modify by moving one of the points around so that the rest of them keep staying on the curve.

Is there a functionality for that? How could it be accomplished?

I think Spline Mods sample should work for you. It defines the curve using interpolation points and then allows changing one of them. It is 3D, but the interface is nearly identical.
