This is our Logo. See how it is an isometric view of an angular robot hand? Well, it sure looks like it started that way.
My initial goal was to convert this image into a descriptions of lines so that we could create a logo for our printed circuit boards. It should have been easy: line from a to b, circle at x, y with radius r, etc. But, those black lines you see in that picture are not actually black lines. They are areas defined by zero-width line edges. Finding accurate endpoints for those lines was annoying.
So, I quickly thought it may be easier to re-create a 3D model and then project those edges to a 2D plane. That was not easy, yet, perhaps, it may have been easier than the original goal.
Now we have a 3D model of the robot hand, plus a projection to a 2D plane.
This line drawing is scalable in an Excel spreadsheet, and creates a Script file to use in Eagle PCB layout.
This is the bonus:
