Extrude Point

In order to extrude a point, Grasshopper wanted me to create a planar surface in Rhino.

1) I used the four point surface tool and created the surface shown above.

2) I created a point within this surface.

3) I selected the surface and opened it in Grasshopper.

4) I then linked the “surface” command in grasshopper to my plane, and did the same thing with the point I created.

5) I connected these with the “extrude” command in Grasshopper and completed the circuit with a Brep.

This is the set-up needed when one wants to take a point out of a planar surface and extrude it.
