How do I change the size of my workplane in TinkerCAD?
1) On the lower right hand side you will find the "Edit Grid" Button.

2) Click "Edit Grid".

3) The settings box will pop up. The size of the grid is set via the boxes that say "Width" and "Length"

4) Change your units and hit "Update Grid" otherwise your units will not change.

5) The workplane has gotten bigger!
