Welcome to the forum ..

There are quite a few different ways:

Subtract/Cut

Derive

Scuplt

Multi-body part

have you gone thru any of the tutorials?  There should be some good examples there ...or you can google it and find a lot of Youtube, Screencast videos

This link has results showing most of the ones above that I listed.

if i have sphere in part mode, what is the best way to cut it? because as a separate part I use split tool but if part already have something and i want add this sphere, plane no passes through and can't select the cut line.. I can combine it in assembly, but seems it's not the best idea create separate part only for sphere=)

what i m doing wrong?

share what you have .... but why do you need to cut it ?

Maybe redraw it so you're on the origins. It's (in my opinion) to model from this area, it;'s giving you free planes, axis's  and origin point.

You can make it from a revolve ..

You can do it with a multi body with each being a half.

just hollow hemisphere created with revolve  and plane where i want cut it and remove one part. so I cut it with the sketch from the side, but not sure if this way is the best

[mdavis22569]

If you want to remove from the half to the work plane

You can cut it from the top down, or you can make a rectangle/sq on the work plane and extrude cut it from the work plane out ...

Can use the split tool and make it 2 pieces...

Again, I would go to tutorials or YouTube videos and see how some the examples work.

Looking for boolean operation like cut of two shapes, because boolean subtract is not the way I think

for example if I want cut difficult structure from one cube inside another to get something like cast and mold, or same, just cut intersected zone from one of two intersecting spheres?

[mdavis22569]

you could derive subtract or sculpt 

the subtract is what they did in the video

here is sculpt

for what you're explaining ...I'd probably use sculpt ...but that's me
