Hello, i'm new to forum and very much a beginner :)
How can i cut or change my nurb surface? I'm having trouble figuring out how to define a shape onto a surface and then removing a portion to make a hole or freehand it in half in a certain way.
For example, how could you take a nurb sphere and cut a hole onto the surface then remove the unwanted part?

Thanks for any help, i hope this is possible :)
