# CopeTube

Interactively design precise tube-notching [templates](http://www.eaavideo.org/video.aspx?v=595079996001) and export them as SVG files for printing to sticky labels.

Tube notching is commonly performed in steel bicycle, aircraft, roll-cage, and handrail fabrication.  

CopeTube's templates make it easier to cut fish-mouthed tubing junctions by hand instead of using bulky and expensive metal-notching machines.

Template options include:

* measurement units

* phase lines

* labels

N-many-tube & non-round-tubing templating not yet supported.

  * uses jQuery & Canvas! But code is .min.js only :-(

  * it's [JS](http://cq.cx/js/tubejoin.js): bespoke PDF, DXF, UI generators and a ThreeJS renderer!

## Hacking

* Uses [Svelte](https://svelte.dev) compiler for UI reactiveness

* Uses [vite](https://vitejs.dev) for webpacking and dev (`make run-dev`)

## Ideas for future

* make modeling components finer grained so they can be used as instanciated within cells of an [Observable](https://github.com/observablehq) [Notebook](https://github.com/gzuidhof/starboard-notebook)

  * would allow an ad-hoc means of persisting and tweaking full build worksheets of (bikes or other tubed things)

* 3d joint-modeling component for a richer preview?

* GUI for laying out a [basic "Nine Tubes" road bike frame](https://github.com/occamsshavingkit/Bike-Draw)

  * take cues from [JS.Sketcher](https://github.com/xibyte/jsketcher) for the UX?
