I definitely need help.
I want to create a surface, which is a variable offset of a given one (Surface Nurbs in my file), in a range between 8 and 14mm (±1mm). And I want to create this surface in Grasshopper.
It has to be:
A really smooth surface with no visible bumps.
It should “cover” the volumes (the 8mm thick red and the 14mm thick orange in the file). I create some “fake” sections, just to give an example of the transition between the two volumes, but it’s just a reference and I don’t need a huge precision.
Everything’s shown in the pic below:
Yes, these are the starting volumes.
What I want to achieve is something like this, so I use the Graph Mapper that you suggest me in the other topic, trying to have something simple but with a decent control.
It’s fine in one direction (let’s say in U), but not in V (as you can see the GH surface needs to be slightly wrapped here on the bottom and on the top, in order to get close to the red volume)
So I’ve tried to add a second Graph Mapper in order to control the V flow and a Cross Reference (to keep the two G.M working), but it wasn’t a success. Any suggestion?
Is it possible to add several Graph Mappers, both in U and V, to better control the offsetted surface? (I don’t need it right now, though).
I was still working on your previous thread:
