I'm joking! RhinoNest doesn't think, at least in 2.0, but I would like to explain how it works, and it will helps to improve our results.
RhinoNest is based on a Heuristic Algorithm
, basically this algorithm, improve the result as more time we invest in the computing.
For example, when you do a nesting, get 10 possible solutions and based on the two best solutions, go on computing a better result, and so on... After RN spend the maximum time, show us the best solutions that it founds.
Based on this idea, if we define in Freedom 90º or Free, it affects to the result in quality terms. When you select 90º degree of freedom, each object has 4 possible rotations, and the algorithm can spend more time to improve the position. If you want to do a nesting of some rectangles, and you select Free, the algorithm will spend more time in orientation, and will spend less time in position.
Other important point is the Maximum Time. As more time we define more possible solutions RhinoNest will find, and the result will be better. I recommend you use the maximum time possible, at least in Freedom Free.
If you have any doubt, don't hesitate to contact me.
