Delete horizontal edges or do loopcuts in geo nodes

Hello!

I’m trying to do a simple thing that i can do in traditional way but in geometry nodes, and i’m having too much trouble. I was researching for it but i didn’t find out. I watched some videos about indexes, but some things didn’t make sense to me.

Here it is.

I’m trying to do this steel trusses procedurally:

So i was trying to make a base poly mesh that i can edit easy in the viewport, make some cuts, triangulate, convert it to curve and do a profile curve like an iron bar like this:

There is a way to delete this lines after subdivide or just do loop cut inside a base mesh in geo nodes? Maybe I’m thinking wrong the way to do that?

So, if anyone can help me to understand it, i’ll apreciate :slight_smile:

Hello, there are multiple ways to do this, but instead of removing the loops, I would simply assemble the curves.

ps: when you really need to use your approach, you can see simple setup below:

wow, thank you very much.

This solve my problem and i like both ways you came to the solution for this. I confess its confusing to me yet about the way you manipulate the vertex and edges, i need to study more about it.

But i think the first way is more friendly to work, sometimes i think in the traditional way but there is more inteligent ways to do it in geo nodes.

Thanks again! :smiley:
