It is really cool that you can take simple geometric figures (rectangles, pyramids and cones) and turn them into something really amazingThis was my first time using TinkerCAD, so I took lessons on how to use the basic controls. Then I figured out how to make the shapes so they were hollow and would make a mold. From there, I made a simple castle (the base and towers) and then added multiple floors, putting spires around the edges to give it an unwelcoming feeling (and make it look cooler!). Then I added stairs.
