Nesting BLF Naive

NestingBLFNaive (Bottom-Left-Fill Naive) is a simple rectangle nesting algorithm that places items sequentially into a container by always positioning each new piece in the lowest possible position and then the leftmost available space. It does not perform complex optimization or backtracking; instead, it follows a straightforward greedy placement strategy.

Output ports

Name	Type	Description
Sheets	Curve	Sheet boundary curves. Flat array of rectangular curves representing each sheet used in the nesting.
Geometries	Geometry	Nested geometries in their final positions. Flat array of all geometries in the order they appear across all sheets.
Move Vectors	Vector	Translation vectors for each input geometry. Array aligned with input geometries showing movement from original position. Unplaced geometries have zero vectors.
Rotation Angles	Number	Rotation angles in radians for each input geometry. Array aligned with input geometries showing rotation applied. Unplaced geometries have zero rotation.
Sheet IDs	Number	Sheet index for each input geometry. Array aligned with input geometries showing which sheet each geometry is placed on. Unplaced geometries have value -1.
Geo IDs	Number	Original input geometry indices. Flat array showing which input geometry corresponds to each nested geometry.
