I’m creating a model to 3D print. I have a body with a hook on one end with fillets all around one side. I want to create the inverse of the body so I can join them together after printing. I’m trying to figure out how to do an inverse (or reverse) of the top body so the flat side will face the bottom body but with the hook reversed so it will line up.

Also you can split body in half using split tool. So you can design it as one part and then split for printing.

OMG! I tried the mirror tool but couldn’t figure out how to use it. Thanks so much for your video, it made it so simple!! ❤
