How can I show surface curvature with contour?

Hi guys,

Thank you all!

Hello
You could use Mesh Iso Splitting

With my plugin Nautilus or the component that is somewhere on discourse.
here the version with just one value.

Dual color model design

I am trying to design a dual color model to 3D print and know that I need 2 STL files (one for each color). As a test, I took an egg/oval shape and then applied a displacement using a black and white texture. In other words, I used the applydisplacement to “carve/engrave” into the egg surface to get grooves in the egg surface. My goal was to obtain the grooves or carvings to use as the 2nd color STL model by Boolean difference of the engraved egg with the original egg. I have attached a file th…

Thank you so much, @laurent_delrieu! That’s really a fantastic tool!
However, I download your plugin, when I open GH, it shows the errors like:

Hi Laurent,

Thank you for your suggestion.
I am using a campus computer and I can’t update my software now.
And for the other version, I can’t figure out how curvature is displayed using the C# component.
Anyway, thanks again for your kind help!

The C# is quite the same. Input a mesh, input all weights (curvature here), then input IsoValue you want to display.
The outputs are meshes so use Mesh Edge component E1 to get the naked border
