I know I never got to make the video showing this node setup but there is this one here that follows similar principles, so check it out if you are interested: ruclips.net/video/fD9NIItWBbk/видео.html

Seriously this one should be solved by devs, it was reported very long time ago (T80979), and devs said well this is not a bug it's just lack of setting in geometry nodes... lack of setting that produces bad geo since forever.
Does this still work in Blender 3.3; or later versions; Gave it a quick try and the issue still persist on my end unless Im doing something wrong; It acts a bit weird of path curves, like second point shrinks down to 0 radius.
It should work fine with 3.3. Can you explain what exactly goes on with your example? You can visit my Discord channel and send some files or printscreens there. discord.gg/6kxQ5vKeVg
Nice solution, thank you so much. When I set resolution to 4 I get an extruded diamond, is it possible to extrude a square instead? like rotate 45 degrees. Actually it would be nice to set a width and height independently so I could get an extruded rectangle.
Well, the short answer is no. We need to extrude profiles that are simmetrical on all possible axis. And there is only one shape that has infinite simmetrical axis, a circle. That is just the way this node is built. Something like the thing you're asking could maybe be build but only for 2d curves. And that is a task for another time since that problem should have a totaly different approach that the one I took for this node group
I was finally able to create a node setup that extrudes custom profiles along a path. If you're interested, check it out here: ruclips.net/video/fD9NIItWBbk/видео.html
Really great stuff ! Well done :) But ... I've noticed a very little issue : on your sphere example, if I use a 4 sided shape, I can see that the horizontal extrusions are not aligned with the original normals of the mesh, so the points position of the generated tubes are not always matching at the intersections. There is also a little gap at each intersection, because the tubes ends are not merged, do you have any plan to fix that ? I know, this is a difficult one ;)
If you're talking about using meshes that have more than 2 edges that share a vertex as your start geometry, then you'll never be able to have a smooth transition of the tube over a vertex and you'll always have gaps. This works "perfectly" just for curves. And meshes that don't intersect more than 2 edges. But that's just a limitation of Blender (for now?) If you try to use a wireframe modifier, for example, you'll get the same issue.
@@BlenderBash The skin modifier generates smooth transitions on vertices sharing more than 2 edges, but it's another (slower) way of doing this. ;) But my first remark was about something else : if you use a 4 sided extruded shape and have a close look at the horizontal edges of the sphere, you'll see then the vertices ar always aligned horizontally (or vertically) instead of following the sphere normals. By looking at your nodes setup, it seems that this part is mainly done by original nodes and not your setup which deals with other cases.

Yeah, I am very interested in seeing your solution to this annoying issue!

Hi,I bought this. What if I want to extrude with an arbitrary curve?
Seriously this one should be solved by devs, it was reported very long time ago (T80979), and devs said well this is not a bug it's just lack of setting in geometry nodes... lack of setting that produces bad geo since forever.
If someone was really interested, it could be fixed. We don't need to wait for the Blender Foundation devs.
This is a really cool set of nodegroups however I must say it is vastly limiting that you are not able to set the radius for each curve point.
Hi, I want to purchase your noda but will it work with newer versions of blender (4.0). Or is there any way to fix it for the new version?
It worked on my star. In my situation, the BB_Tubes Node only was perfect - thnaks
could it create pipes selecting only parts of the curve?
Thanks, it helped me a lot:)

@@BlenderBash by setting the resolution to 4 for the extruded shape along the edges.
