# CADAM Benchmarks
|
|
|
|
A showcase of what [CADAM](https://adam.new/cadam) builds from a single plain-language
|
|
description. Each benchmark starts from the prompt shown and comes out as fully parametric
|
|
OpenSCAD — adjustable dimensions and colours, ready to export as `.STL`, `.SCAD`, or `.DXF`.
|
|
The `.scad` source for each model is included here, so they double as a record of how well
|
|
CADAM turns plain language into real, printable, fully parametric CAD.
|
|
|
|
### Complex machines & assemblies
|
|
|
|
| Model | What it shows | Controls |
|
|
| --- | --- | --- |
|
|
| [V8 engine](13-v8-engine.md) | complete V8 — banks, heads, valve covers, manifold, headers, crank, pistons, oil pan | 22 dims · 8 colors |
|
|
| [9-cylinder radial aircraft engine](10-radial-aircraft-engine.md) | nine finned cylinders in a radial star + prop hub | 15 dims · 6 colors |
|
|
| [Turbofan jet engine](11-turbofan-jet-engine.md) | full engine — fan, bypass cowl, core stages, exhaust plug | 2 dims · 10 colors |
|
|
| [Axial turbine blisk](12-axial-turbine-blisk.md) | ring of twisted aerofoil blades on a keyed hub | 14 dims · 1 color |
|
|
|
|
### Parametric fundamentals
|
|
|
|
| Model | What it shows | Controls |
|
|
| --- | --- | --- |

|
|
| [Knurled control knob](02-knurled-control-knob.md) | diamond knurling, D-bore + set screw, pointer | 15 dims · 2 colors |
|
|
| [Hex bolt & nut](03-hex-bolt-and-nut.md) | **real ISO threads** (BOSL2 `screw`/`nut`) | 3 dims · 2 colors |
|
|
| [Honeycomb bracket](04-honeycomb-bracket.md) | generative hex lattice, filleted L-bracket | 13 dims · 1 color |
|
|
| [NACA 2412 wing](05-naca-airfoil-wing.md) | true airfoil from the NACA equations, tapered loft | 9 dims · 1 color |
|
|
| [Threaded jar & lid](06-threaded-jar-and-lid.md) | two **mating** threaded parts | 9 dims · 2 colors |
|
|
| [Bevel gear drive](07-bevel-gear-drive.md) | meshing bevel gear pair at 90° | 9 dims · 3 colors |
|
|
| [Centrifugal impeller](08-centrifugal-impeller.md) | 7 swept backward-curved blades | 10 dims · 1 color |
|
|

## Regenerating the GIFs
|
|
|
|
`render.sh` turns any `.scad` into a clean orbiting GIF (and, with `--sheet`, a
|
|
4-view contact sheet). It mirrors CADAM's own preview: BOSL2 on the library path,
|
|
`color()` parts preserved, a clean orbit around the vertical axis.
|
|
|
|
Prerequisites (macOS shown; any OpenSCAD ≥ 2021.01 with BOSL2 support works):
|
|
|
|
```bash
|
|
# OpenSCAD CLI + ImageMagick
|
|
brew install --cask openscad@snapshot
|
|
brew install imagemagick
|
|
|
|
# BOSL2 (and BOSL) on the OpenSCAD library path — these are bundled in the repo
|
|
mkdir -p /tmp/oscad-libs/BOSL2 /tmp/oscad-libs/BOSL
|
|
unzip -o ../public/libraries/BOSL2.zip -d /tmp/oscad-libs/BOSL2
|
|
unzip -o ../public/libraries/BOSL.zip -d /tmp/oscad-libs/BOSL
|
|
```
|
|
|
|
Then:
|
|
|
|
```bash
|
|
./render.sh 03-hex-bolt-and-nut.scad # -> 03-hex-bolt-and-nut.gif
|
|
./render.sh --sheet 09-herringbone-planetary-gearbox.scad # -> *.sheet.png (inspection)
|
|
```
|
|
|
|
Knobs (env vars): `FRAMES` (default 36), `SIZE` (520), `ELEV` (62°), `FPS` (24),
|
|
`COLORSCHEME` (Tomorrow), `OPENSCADPATH` (`/tmp/oscad-libs`), `OPENSCAD_BIN`.
