IndexGroup ByIndices

[Peter_Dragovic]

Hi there all
Has anyone had issues with using IndexGroup.ByIndices for 3 indices, but always get 4 indices as result? Or did i miss something?
Tnx in advance

yes thats intresting

You don’t need the D value. There will be assigned a value but it won’t change the result.

Well i dont need it of course But problem is when i try to create mesh from TIN surface i do need just A B and C values, otherwise i get error.

[Deniz_Maral]

I have created also with 3 indices and without error. Is everything ok with points and indices?

[Peter_Dragovic]

Yes it is. I think problem is when you have TIN surface, mesh requires 3 indices , not 4.

This looks like buggy behavior - I have logged this into our backlog

Tnx @solamour.

It works on my side. I saw it, too but it did not make a problem for my case.

Did you make that conversion?

Why this conversion for? It does not apply to my code, and also mine is not working as yours.
