POSSIBLE BUG SRC 8.16.25028 - TriRemesh

Hi Fellas,

Looks like there´s a bug on the Extrusion and TriRemesh components. As far as I can remember, extruding a trimmed surface should output a closed extrusion, which is not my case here. Regardless, TriRemesh should have no problem to convert an open extrusion, which is also not happening resulting in an invalid mesh.

Hello
Ahhh Ahh you are a little comic ! Why putting a component exactly on another wire !


Indeed it is connected like that

Seems good to me

And for the problem of Triremesh, I often input a mesh in Triremesh as I found that more reliable

Yep, my bad as far as the (non-existent) extrusion issue goes. I was initially reporting the TriRemesh bug only and while fiddling with the code (trying to figure out the culprit) I ended up overlapping the wires, which led me to believe there was also a problem with the extrusion component. Nonetheless TriRemesh is indeed bugged as far as I can tell.

Yes Triremesh has some bugs but if you input a mesh it will work far better. Just a workaround.

Thanks for the workaround tip @laurent_delrieu , much appreciated.

Hello! Could you tell me where I can download TriRemesh? I can’t find this tool, it gives me this error: 404: No package found by the name of ‘Kangaroo2 Components’.

Failed to install the missing plug-in.

Not all plug-ins were found on the package server.

thank you

Hello
I am not the developer. I think Kangaroo 2 is installed by default on Rhino 7, 8 … like Grasshopper. Perhaps you have an old version ?

You can try the remesh by color component instead. I think it existed before TriRemesh. Or depending on your version of Rhino also MeshMachine.

If memory serves, TriRemesh used to be part of Kangaroo 2 and later became part of Rhino 8 under Mesh>Triangulation, being removed from K2. Please don´t quote me on that as I´m old.

This will be included in Grasshopper in the next Rhino 7 service release candidate.
The new component will then appear at the bottom of the Mesh>Triangulation tab.

The issue with extrusions is simply a casting one. Connecting it via a Brep component ensures that it will be recognised and meshed correctly:

Triremesh comes installed with Kangaroo2, which is included with Rhino. It shows up under the Mesh>Triangulation tab.
