OpennNest-Woodpecker. how to optimise the individual panel arrangem

Hi, I noticed from reviewing the algorithm and files on the forum regarding OpenNest that you can adjust the rotation and seed settings to achieve a more optimized and aligned arrangement in OpennNest. Are these changes based on randomness? My question is, how can we easily determine the optimal rotation and seed? This is especially important when dealing with a large number of different pieces. Is there any reference file or method to do this.

How can we transfer the obtained geometry to the Woodpecker “BTL part from Brep” plugin in Grasshopper to create fabrication files? I aim to ensure that each individual panel, along with other related panels on the same sheet, is processed together for fabrication, rather than independently.
