Hello, You can use this spiral tool to create spiral curve and then spirals around spiral curve. [image] Spiral tool for grasshopper Grasshopper Here is a script (a gh) not a component (gha). [image] spiral_with curve.gh (7.2 KB)

Thank you for your reply! Do you know the way of making the square pipe as shown in the picture so that it has those sharp edges?

Just make a tapered extrusion and use the Twist component.

This is amazing! Thank you guys, that’s very helpful

@aleksgutkowska , you can also combine parts of Laurent’s with my script, if you want to have a quad mesh, instead of a triangulated one. Only the end caps are hard to have as quad geometry, since their boundary is polygonal with more than 4 vertices. [Screenshot 2020-01-04 at 08.23.15] spiral tor…
