I get this uneven surface using Dendro in GH1

My GH script:

DendroThickness.gh (10.1 KB)

[Quan_Li]

Use R8 Shrinkwrap instead.

For this kind of geometry (not a volume) @Quan_Li and @leopoldomonzani are some of the best answer, but there are also many other solutions to offset !

But as a regular user of Dendro I know that the other proposed solutions are not perfect. Shrinkwrap just do boolean union, there is no difference or intersection.

Mesh boolean in Rhino is (was) less reliable than Dendro.

So with Dendro if you need a not rounded offset, use Leopoldomonzani mesh in Dendro. If rounded is good I propose you this.

or populate the surface with a lot of spheres, do not use Populate geometry because it is too slow. use Nautilus plugin or other tools to populate a mesh.

The native RhinoCommon Mesh.Offset might also be an option:

Of course, I know about Shrinkwrap and Mesh.Offset, they work on this part, but if the part is much more complex, they won’t cope, and then you need Dendro, which works on anything.

I found a way to solve my problem:

1. Right-click on the S input of the Mesh Grid and select Set Mesh Options, then make more polygons.
2. I set the Number Slider to 10 and connected it to the B input (“Bandwidth”).’

I didn’t knew this limitation with Dendro. But from what I read in documentation it seems Bandwidth has to be related to the maximum offset and vowel size. So the bigger the offset the bigger the bandwidth!

Here 10×0.3 > 2 so it is ok
