Hi
I am trying to create a reactor with a torispherical base in gambit. A torispherical dome is as shown here:

I have created a sphere and a torus as shown in the above link and have tried to subtract,split,intersect the volumes to get my desired geometry but nothing seems to delete the unnecessary portions of the geometry. I am using GAMBIT version 2.

A clearer picture of what I want to create is shown below:

Please help me figure out how exactly to edit the sphere and the torus to get the required geometry.

Thanks for your time and effort.

PS: Really sorry for posting in the wrong forum. Didn't notice the Geometry forum earlier. Now, unable to delete this post and re-post it there.

Cheers
