I create a surface with some curves. Now I want to change the surface a bit, I use the curve I made earlier but the surface doesn’t change. Curve control points move but the surface does not change. Does anyone know how to fix it?
Which command did you use to create the surface? Which version of Rhino?
Not all commands are “history enabled” so that the result of the command is updated when the input is changed. Also it is possible to “break history” by certain subsequent operations.
