Answer 3

its depends on what your scene file contain. if there is a complicated scene, like lights, render setting etc. propablly you couldn't. but if you only want to open a model, you can export it. FBX, OBJ are the most popular formats you can use. Besides, there is a new common format called Alembic. It can be very helpful.
