CAD

We made a key chain in tinker cad. We learned how to join and unjoin objects. We also learned how to make holes in objects.
Then we learned how to find shapes and texts. After that we learned how to make work planes.
Finally I made A table out of gears a cylinder and the paraboloid. I started with the gear for a base. Then I put a cylinder on top. Then I stacked paraboloid together. Then I cut out a gear in the table and place another one in there.
