Intersection of point extrusion and geometric primitives

Grasshopper

Hi0 all,

I have a point cloud of a surface, that I would like to extrude in order to create a volume (iges or step file).

I did the construction process with Rhino:

  • creation of a curve on the border of the points
  • surface patch on the curve
  • extrusion along the Z axis
  • intersection of the extruded volume with a cylinder

Now I woud like to do the same with Grasshopper.

I achieved to create an extrusion from a mesh and to save it (with the Pancake library)
I also achieved to create a pipe (Axolotl library)
But I didn’t manage to combine both, i.e. to create the intersecting volume.

Maybe someone can help me further?
Thank’s,
Yannick

I see no cylinder (or “pipe”)? What does SubD have to do with this?

P.S. Is this of any use?
