At first, we started with just a sketch. Then we were able to revolve the sketch around itself to make the base of the rook. Then we selected surfaces and had different options like extruding the selected surface and creating new sketches on top of it. When we got to the top of the rook, we used a linear pattern with another sketch to make the same sized sections coming out of the top. After that the sketch was finished and so was the rook.
