This is my experimental setup right now:

Your setup is in 2D !!!
You just have to use Revolution component

If 3D/SOLID :

Change the axis of revolution and add Cap Holes

You’ll find a general way with mesh here,

"Unsolvable" geometric problem

I got a strange question. The goal is to push a cylinder through a block while it gets rotated by 90°. As it is not possible to sweep a surface, I can only get near to the correct result. See this: [image] The cylinder cap makes an interesting surface, which shall be exact (and not as in my approach). Any ideas? CP_CylinderChallenge.3dm (255.1 KB)

I have made a plugin that do quite the same thing but not exactly

Nautilus plugin

Nautilus is back! I added some components. Component to outputs fonts and text as curve, surface or brep [image] One component to cut a mesh/brep rotate the part and link the 2 parts. [image] A tool to calculate the radius of branches of tree [image] A tool to envelop a network of lines (that lies on a surface or a mesh) [image] A tool to carve a mesh with deformed ellipses [mesh carving3] A tool to add arc on a polycurve [image] Spiral on a sphere at constant distance. …
