If you have a 3D platformer level, you will be able to convert it into any other level type. Unlike 2D platformers, these cannot be added onto with more ground, but they can be extended. In 3D platformers and most of the other game styles, you will start out with two platforms (or planets in Super Mario Galaxy 2's case). In 2D platformer levels, you will start out with a blank level. The player may place any enemies, blocks, power-ups, or other things eg may want in the level.

As in the first game, Super Mario 3D Maker utilizes the GamePad as a level creator.
