Tinkercad Basics
11. Shapes
The best advice for taking advantage of this step is to spend time looking through all of the shapes and pull a few out onto the workplane and see how they can be adjusted. Some of them have some neat functions. Some things to know:
1) Click the little star to "favorite" shapes that you use often. This will help you find them quickly.
2) Don't get mentally stuck on the premade shapes. The best part of Tinkercad is making your own shapes by grouping the premade shapes together and cutting holes out of them.
