I have a surface that is shaped like a sphere. I want to convert this to a sphere with a hollow inside with an escape hole for 3d printing.
I read some things on the forums how surfaces are not sphere but I am kinda lost.
What I have is
2 spheres with centers on the 0,0,0 origin. One has a diameter of 3cm. The other has a dimeter of 2.5 cm.
How do I
- Subtract the volume of the smaller sphere (surface) from the larger?
- Make a cylindrical hole in the outer sphere to the new empty area?
Best,
a
