[Newbie's Question] How do I add Thickness to my Parametric Wall (Grasshopper Plugin too)

So Basically I am trying Parametric Design with Rhino. Problem is after experimenting it and baking it, I am unable to get Thickness from it.
I tried using ExtrudeSrf command on Rhino to create the thickness but there is crazy amount of “vectors” from it and it just doesnt extrude (after waiting like 10mins). And I also realise this method will not make it into a solid. It will just be a Hollow thickness if you know what I mean?

So how do I add thickness to it? In BOTH Rhino and Grasshopper. Thank u guys in advance :slight_smile:

Rhino does not make or work in Solids. It makes Breps which are hollow. https://en.m.wikipedia.org/wiki/Boundary_representation

How about this:

  1. If possible, in GH make the wavy geometry into a single Open Brep
  2. Move 1 up the distance you want the thickness to be
  3. Use Brep Edges to get the outside (naked) edges of both Breps
  4. Use these 2 edges to make either a Loft or Ruled surface
  5. Join 1, 2, and 4 to make a closed Brep

Offsetsrf (offset surface) should do the trick in rhino. I assume grasshopper has a similar function which you can attach to a slider.
