Not stupid, just a common misunderstanding about how AC works. In principal, there is no reason that one could not save from a 2D view - saving what WOULD be generated in the 3D window, given the marquee, cutting planes, etc But, historically, AC has only offered saving to 3D formats from the 3D window itself.
Almost everyone has run into this at some point.
