Slicing and nesting working together

The initial idea was to slice 3D models into a sequence of thin slices. Once that was working it was suggested that thicker slices may reduce the total machining time.

The problem is that vertical cuts for the slices will create an ugly rendering of the desired surface that will later need to be fixed by an artist.

The next idea was to put together the milling action for each slice sides and the nesting algorithm that will distribute the slices into the available stock sheets.

As usual it is easier to say than to do, and though it seems Aspire and Rhinoceros allow you to do a similar process, my code is now performing both tasks without user intervention. Blue or green color on the outline represent whether the slice has to be flipped or not (each slice has to be machined from top to bottom).
