My first project as a scratcher. As always use Turbo Mode. Press space to create a X*Y*Z Rectangular Prism. (You choose the params:) Press c to clear the field. Version 2.0 lets you choose the size of the shape.(Please choose a length over 15 scratch starts breaking down with the pen function and direction function at this point.)
JSI!!! Learned it from thinking about the structure of 3D graph paper.
