- Try all valid best fit pairs instead of only the first when qty=2, picking the best via IsBetterFill comparer (fixes suboptimal plate selection during auto-nesting) - Pre-compute best fits across all plate sizes once via BestFitCache.ComputeForSizes instead of per-size GPU evaluation - Early exit plate optimizer when all items fit (salvage < 100%) - Trim slide offset sweep range to 50% overlap to reduce candidates - Use actual geometry (ray-arc/ray-circle intersection) instead of tessellated polygons for slide distance computation — eliminates the massive line count from circle/arc tessellation - Add RayArcDistance and RayCircleDistance to SpatialQuery - Add PartGeometry.GetOffsetPerimeterEntities for non-tessellated perimeter extraction - Disable GPU slide computer (slower than CPU currently) - Remove dead SelectBestFitPair virtual method and overrides Reduces best fit computation from 7+ minutes to ~4 seconds for a 73x25" part with 30+ holes on a 48x96 plate.
