3 Extruders Geometry nodes in Blender

These are 3 node groups that extrude a profile curves along another curves. Sounds like not that big of a deal, but if You watch this showcase video https://youtu.be/fD9NIItWBbk, you'll understand why IT IS A BIG DEAL :)

Blender out of the box extrudes profiles from curves in a very bad way, deforming the thickness of the pipe (tube) based on the angle between two edges. These node correct this behavior.

You'll get a Blender 3.2 file with 3 Group nodes:

1. BB_Tubes creates pipes (tubes) from multiple curves or meshes.
2. BB_Upright Extruder keeps the profiles upright (Extremely important for roads, ramps or paths)
3. BB_Extrude Along Path simply extrudes a custom curve profile around a curve following curves natural tilt.
