I would like to have a parametric offsetted surface with different values, starting from a given one (please check the file attached).
It will be great to have a good control all over the surface, adjusting the values in certain areas (for example 15mm of thickness in the border / red area, 20mm in the yellow one and 10mm in the blue area).
Yes, it was a SubD since it’s usually easier for me to adjust the basic surfaces in Rhino, but when I start working in GH i transform the SubD into Nurbs (the final output would be a iges/stp).
WB seems to be powerful for my needs, is it possible to work with nurbs too?
I guess I need to keep two separate nurbs, the “starting” surface and the “variable offsetted” surface, since after that I need to make several nurbs commands (trims, fillets, etc). The first will be the inner skin of the product that I’m modelling and the second will be the outer skin (it’s basically a shield, with holes, profiles and so on).
To create a surface from a mesh, the Warp Weft component can be used to extract two lists of mesh edges. These edges need to be joined into polylines and converted to curves and sorted ascending in X and Y to create a network surface.
The easiest way to create a smoother transition is to smoothen the mesh. You could also use some sort of an attractor or remap the numbers based on distance to the curve but that’s more complicated.
Thanks for your solution. I’ll try it with the normals instead the Z on the surface that I’m working on now.
Which is the smartest way to have a transition range (so some smoothness) outside of an area?
As shown in the image below, with the max thickness (let’s say 20mm) inside the yellow area, the transition between the yellow and the blue and the min thickness outside. My aim here is to have a really smooth transition, better if the areas are not visible and the surface doesn’t shows “bumps”.
