I’ve forgotten the name of a command in Rhino v6 that does exactly what I need for my current project. It’s used to deform surfaces. It allows you to select a control point on a surface and move it using the gumball, however instead of moving just the selected control point it also slightly moves surrounding control points. For example, if the surface was a simple rectangular plane, this command would allow you to select and drag a single control point to create a Gaussian-like deformation in the plane. Any help towards identifying the name of this command would be greatly appreciated.
Thank you for your time.
