Introduction

What is the Sandbox?

The Sandbox is a workspace for trying cutting plans without touching live production. You can re-optimize, hand-build patterns, add or drop widths, and change weights freely; nothing you do there affects a running run until you explicitly apply it.

Two Kinds of Sandbox

• Run-linked — created from an existing run (its "Sandbox" button). It starts as a copy of that run's plan, can be re-optimized, and can be applied back to the same run.
• Standalone — created from scratch on the Sandbox screen ("New Sandbox"). You add your own widths and build patterns by hand; when you're happy, you turn it into a brand-new production run.

When to Use It

• A customer changes a width after the run is planned — model it before committing.
• Test whether adding a small extra width lowers waste, without disturbing the committed plan.
• Try a hand-built pattern structure the optimizer wouldn't pick.
• Re-optimize with a tweaked blade or deckle override and compare.
• Plan a run manually from first principles, then create it.

Isolation

Sandbox edits are isolated. A run-linked sandbox only changes its run when you apply it, and only while that run hasn't started yet — once the run is In Progress the sandbox locks. You can keep several sandboxes and delete the ones that don't pan out.
