I was having a hard time creating an object. Dan made it look easy. I tried designing a star shaped cookie cutter, but I could not get the other side to be hollow. I tried using shell, but it continuously prevented me from doing it. Instead, I used the star design to make a little container for jewelry. It is like a little plate that you could put rings, earrings, etc in. I hope with more practice I can get better with Fusion 360.
