Try the original example before buying
Inspect the complete fictional example and illustrated quick start before buying. The paid ZIP adds the editor for your own measured plans.
- Enter measurements once: Use the same measured run and allowance in route cards and stock totals.
- Keep passes and order explicit: Record ordered attachment points and installation prerequisites.
- Take the plan to the bench: Export a PDF work pack alongside SVG, CSV and editable JSON.

What it helps you do
For model makers planning their own rigging work. Enter model-size coordinates, ordered point passes, material families, measured runs, allowances and installation notes.

A practical example
Mira training layout
Start with
Six fictional model points, one 0.25 mm training-thread family and three entered measured routes. The scale label is 1:72.
Get this result
The initial total is 196 + 171 + 171 = 538 mm. After the allowance change it is 196 + 176 + 171 = 543 mm. The geometry and measured runs remain unchanged. These fictional measurements demonstrate the workflow; they are not cutting instructions for a real model.

How it works
Enter the measured plan
Define attachment points, materials, routes and allowances in model-size millimetres.
Review the route sequence
Compare side/deck schematics and check installation prerequisites.
Export the work pack
Save project JSON and download the PDF, SVG and CSV outputs.
Before you buy
- Desktop Google Chrome on Linux is the tested environment.
- Extract the complete buyer ZIP and open index.html in desktop Google Chrome. The fictional Mira training layout opens immediately. No server, account or internet connection is required.
- Up to 48 points, 48 routes, 8 material families, 160 route segments and 100 PDF pages. Project JSON import: 2 MiB. A4 and US Letter.
Compatibility & limits
Up to 48 points, 48 routes, 8 material families, 160 route segments and 100 PDF pages. Project JSON import: 2 MiB. A4 and US Letter. Coordinates and lengths are model-size millimetres. The scale is a descriptive label. Cut totals use entered measured runs plus allowances; they are never inferred from the diagram. Side and deck views are auto-fit schematics, not full-size templates or physical fit checks. Crossings are not connections unless the point is listed in that route. PDF project text supports printable ASCII. Saved JSON and SVG/CSV can retain accepted Unicode. Physical fit, historical correctness and other browsers or operating systems are unverified. Tested in desktop Chrome on Linux. Save project JSON to keep your work before closing; there is no automatic save.
