How to generate a solid of revolution from a 2dimensional shape?
Needs Answer
Hello,
I'm discovering GeoGebra 3D, I'm looking to generate solids of revolution.
I drew in 2 dimensions a Reuleaux triangle (wikipedia).
How to create a solid of revolution with this shape ?
I've tried things but I don't get the results I expected.
I need this shape :
Thanks,

A reuleaux tetrahedron is not a simple rotation shape. The 4 spherical surfaces are limiting them selves. In order to create such a shape in GGb you have to calculate the surfaces analytical... this takes a bit of effort and the resulting formulas might be a bit to much for GGb. You can find a example in the attached file.
I remember that there is a much simpler and faster solution in this forum which works with overlapping sphere parts. Sadly i can not find it anymore.
Found them:
With those technices it is simpler the achieve the spherical triangles:
