Tinkercad Basics
4. Left Tools and Moving Objects
Notable items from this lesson:
1) The fit to view tool allows you to zoom in and make any shape the center of your workplane. It is useful because you can use "dummy" shapes to change your view.
2) If you duplicate an object, and move or resize it and then duplicate it again, the new object will be moved and resized the same way. This makes spacing out multiple items simple or making patterns simple.
