Overview

Stop guessing what fits on a sheet.

This tool is for the moment before the shear or the laser when you need a fast answer. You plug in your sheet size, kerf or gap, and a list of parts. It shows you how many fit, what it looks like, and what waste you are carrying.

It is not trying to be a full CAD nesting engine. It is trying to be the fastest way to get to a layout you can trust.

Best for Simple flat parts, quick planning, and sanity checks before you cut.
Built around Real sheet sizes, real kerf, and real shop constraints.

If the layout looks weird, it usually is. Adjust kerf and margins first before changing part sizes.

How to Use
  1. Enter your sheet width and height.
  2. Set kerf or a gap between parts, then add an edge margin if you need it.
  3. Add your parts and quantity. Toggle rotate when it makes sense.
  4. Hit Optimize and use the result as a planning layout, not a religion.

The win is visibility. You see the waste before you create it.

Notes
What it helps prevent
  • Overbuying sheet because the math felt uncertain
  • Layouts that "should fit" but do not
  • Kerf and margins getting ignored until it is too late
What I would add next
  • Preset library for common sheet sizes (48x120, 60x120, etc.)
  • Printable layout sheet for the floor
  • Export: copy part list and layout summary
My Notes

This is one of those tools that saves money quietly. It is not flashy, but it stops dumb waste. If you run a shop, you know how often sheet gets ordered "just in case." This fights that.

  • Start with realistic kerf. Do not pretend you cut with a laser if you are shearing.
  • If the part count is high, run a couple margin values and pick the one that looks stable.
  • For repeat jobs, save the part list somewhere so you are not rebuilding it every time.
