if i make an object in 3d studio can import it in my game and what do i need to do that

If with “my game” you mean your engine the answer is yes, of course.
If you mean “Can I model an object and import it in Quake3 using OpenGL ?”, well I think you are on the wrong forum then.

If the right interpretation is the first one, just look out for some 3ds loading tutorials or save it in ase and give it a look (ase is really a simple format).

Visit also for some samples/tutorials.
There should be a 3ds loading code on FlipCode if I remember.
