Help with geo-nodes pipe generator tutorial

[revolt_randy]

Hi all!

Starting to learn geometry nodes and I’ve went thru a Ryan King Art series on youtube for generating a low poly flower on a curve. Next, I went with a pipe generator youtube tutorial and was doing good at that until I got to the elbow pipe fitting part.

At 10:30 in the video, he starts talking about finding the elbow parts to make an elbow fitting. At 12:50, he starts building the nodes for the elbow. At 15:30, he explains the first part of the node tree. At 16:45, he starts talking about deleting part of the mesh and this is where I get lost.

I get what he is doing, but my node tree looks the same as his, but the end result at 18:22 isn’t the same. None of my starting basis mesh is deleted when viewed.

Here’s my result:

Basically, only the two 90 degree bends should be visible in the 3D view. The parts of the node tree that do this deletion are shown.

here’s my .blend

Using blender 3.6.5

Thanks for any help!

Hi Randy,
you have to change the Data Type of these two nodes to Vector:

Good luck!

Thanks @Zebrahead - that was the part I was missing, changing those nodes to vector did the trick!

Looking at it now, I can see where the problem was. The output of those nodes connected to nodes that expected a vector, so the type needed to be vector.

Thanks to you, I now have a pipe generator
