My apology if this has already been asked (I didn't see it in a quick search).
On puzzles with a guide it's fairly tedious banding sidechain to sidechain or each backbone segment to the proper place on the guide, and seems like the sort of thing software could do very efficiently (and I doubt measuring how quickly people can do this manually gets at the central questions of this whole project - rather, my understanding is it's our human intuition that is on trial here - so we should be getting to that ASAP in the puzzle process).
So my suggestions would be:
1) An "autoband" function for sidechains and backbone nodes (automatically populates the puzzle with bands from each segment to it's corresponding guide - I suppose this could get tricky if there is threading involved, but so far, I've seen no threading on the guide puzzles), or
2) A feature that would flip the reference frame exactly 90 degrees from the current frame of reference (top, bottom, side, side - from current position). If the flip were truly orthogonal I would only need a maximum of two perspectives to place each band perfectly (See "Descriptive Geometry" http://en.wikipedia.org/wiki/Descriptive_geometry for basis of obtaining exact points in 3D given orthogonal projections). If #1 above is implemented, this #2 may not be necessary.
Thanks.
