As the seeker says, he wants to cut sheets of glass. I think he is looking to cut his own reference edge then go from there. It is solvable but it is NP-hard!

I do recall seeing something in the Perl world related to a similar problem. The seeker might look up WARDLEY on CPAN, I think Andy may have done something for optimizing fabric cut-out for kite building.

A good reference on the problem can be found at: "Algorithms and Theory of Computation Handbook", page 19-27, Copyright © 1999 by CRC Press LLC. Which also appears in the Dictionary of Computer Science, Engineering and Technology, Copyright © 2000 CRC Press LLC.
