How does the tool handle vertical grain orientation?

When `grainDirection` is set to 'vertical', the tool swaps the piece's width and length mapping. The intrinsic width is checked against the stock length, and the intrinsic length is checked against the stock width.

Can I use this for standard bin packing without grain constraints?

While you can set all pieces to a single orientation, this tool is specifically built to enforce the restriction that prevents rotation. If you need free rotation, you would typically use a different optimization engine.

What happens if a piece exceeds the stock dimensions?

The `validate_single_piece` tool will return a failure status with an error message indicating whether the oriented width or length exceeded the available stock limits.

The Grain Direction Restrictor is a specialized constraint engine designed for wood and plywood processing. It prevents illegal rotations of material pieces during the cutting process by enforcing intrinsic grain directions (horizontal or vertical). By using tools like validate_single_piece, get_oriented_dimensions, and evaluate_batch_constraints, you can ensure that every piece in your batch maintains its structural integrity relative to the stock sheet dimensions. This is critical for preventing waste-inducing errors in complex bin packing algorithms where rotation is restricted by material properties.
