Ok, thank you Christophe. In the meantime I worked it out generating cones and deleting the surfaces I don't need. So there's no "direct" way to do that from the gui, unless the surface is split so as to have 4 borders...

In your case: Curve Loop(1001) = 21; Curve Loop(1002) = 22; a() = Ruled ThruSections{1002,1001}; > If I switch to the built-in geometry kernel (which I would like to avoid), I > get another kind of error message (1 border instead of 3 or 4). > How can I work this out…? Thank you. Nothing in the built-in kernel can do that: you'd need to subdivide the surface in 2 parts.
