Answer 1

Most of the time, you don't need to pass a rect to function present, unless your swap chain was created with D3DSWAPEFFECT_COPY.

If you want just want to draw subwindows like 3ds max, you should try multiple view or multiple windows in DirectX.

You won't specify any geometry in present, this function just present the content in backbuffer to the display, you should prepare everything you want to draw before calling this function.
