Hi,

I have a bunch of surface polygon meshes like the one on the screenshot where the topology could be much simpler, especially on edges.

How might I get an approximation of the surface mesh by a curve, to get something like on the second screenshot? I'm looking for some node that approximates a polygon surface to a curve with a tolerance parameter for how much of those edge bumps you want to smooth out.

I've been searching the internet and trying with different nodes but didn't find a suitable node or combination of them yet, but can't help but think this is something that must come up pretty often. Is there a node already created for this? If not, how might I approach it otherwise?

Any help really appreciated!

Take a look at this example. maybe this can help you. You need Sidefx Labs installed, as I make use of the node edgegroup_to_curve

Cheers
