Subtract (No solid, region, or surface)

[Bh_GuruCharan]

I was designing a bearing so I am trying to subtract the sphere and the body then it shows no solid, region, surface selected 

I have checked for the solution in forums I tried explode and subtract but makes no difference.

Please some one help me!

SUBTRACT can only take things of the same object type.  The spheres in the top of the ring are Surfaces, and you can't SUBTRACT a Surface from a 3D Solid.  The 14 spheres in isolation are 3D Solids, like the ring.  If I Move those over to the ring, they SUBTRACT from it just fine.

Thanks for replying. I've tried what you said but it makes no difference

What does that mean?  You moved [or copied] the 3DSolid Spheres over to the Ring, but SUBTRACT doesn't work with them [as it does for me]?  Do the moved/copied Spheres actually overlap the Ring's volume so they can be SUBTRACTed from it?  Does it not accept selection of them?  Does it accept selection but the Ring does not get indentations from the SUBTRACTing?  What happens instead?  Are there any messages?  Etc., etc.

That is to be expected because

When you get a chance, convert these like this

Or swap them for these
