Rocket Tool Sketcher Modern

A browser-based rebuild of the original rockettoolsketcher.swf, with a shared geometry model that now also drives CAD export generation.

Current scope

• Supports a Custom mode with editable A-I dimensions.
• Includes the baked-in preset families extracted from the Flash app.
• Uses one shared spindle and rammer geometry model for the browser preview and export work.
• Includes a first-pass screenshot comparison harness for validating ambiguous angle conventions.
• Generates manufacturing exports from Python:
  • combined clean DXF
  • combined annotated DXF
  • separate clean DXF per part
  • separate annotated DXF per part
  • combined STEP
  • separate STEP per part
  • combined STL
  • separate STL per part
  • generated parametric OpenSCAD
  • JSON manifest of the exact derived dimensions

Run the app

npm install
npm run dev

Build the app

npm run build

Generate CAD exports

Example using a baked-in preset:

python -m rts_export.cli --preset bp-core-burner --tube-id 0.75 --output exports/bp-core-burner-075

List presets:

python -m rts_export.cli --list-presets

Example using fully custom A-I values:

python -m rts_export.cli --preset custom --output exports/custom ^
  --a 0.75 --b 6 --c 2.5 --d 0.375 --e 1.5 --f 0.413 --g 30 --h 3 --i 0

Export notes

• The baseline export assumption currently matches the working interpretation used in the refactored geometry model:
  • E from axis
  • G from shoulder face
  • I from face
  • do-not-pass groove modeled as a shallow V-groove
• The generated DXFs use separate layers for visible profiles, hidden bores, centerlines, dimensions, and text.
• The default tooling-set.dxf is the import-friendly geometry sheet. tooling-set-annotated.dxf carries the dimensions and titles.
• STEP, STL, and generated OpenSCAD geometry are written with CAD-interchange scaling in mind. If inputs are inches, the exported 3D geometry is scaled to millimeters.
• The OpenSCAD output is intended to stay editable by changing the input values at the top of the file.

Project notes

• The original SWF export, decompiled ActionScript, screenshots, and the user-supplied manufacturing interpretation notes are all being used to converge on the final geometry rules.
• This is a clean web rebuild, not a Flash wrapper.
• The export backend currently lives in rts_export.
