Model that stands on a flat surface

Hi

I just need to understand something.

When you 3d print an object, is it garanteed to be able to stand on a flat surface?

if so, how can that be ensured?
Where can I find tutorials?

If you model the incredible hulk with just one leg of a flamingo that has all but one toe missing I think it wouldn’t be very stable when trying to keep him standing.

Where can I find tutorials?

Note that you can set the objects origin to its centre of mass from the Origin button in the toolshelf to aid in assessing whether your model may be stable.

Thank you, chap!
