Press space to reset. 1 to fill and un-fill 2 to hide/show variables Use the sliders to adjust size, rotation, and distance. I suggest setting the Z distance to 30 to make it easier to see, otherwise the size of the pen blurs the lines.
Thanks to @MathMathMath for an amazing 3D tutorial. I am hoping to use what I have learned here to make 3D projects in the future. :]
