C4D has multiple undos with 2 paths of undo available. ;0P Maya has undos and so does 3DSMax. 3D programs don't have undos. Where do you get your info? Poser undo sucks. Not only is it one, but it undoes the stupidest things. Set a morph, move camera, undo morph now gone.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
