description: # Cadog evaluation data

This repository contains the evaluation dataset for cadog, CAD web viewer.

As of GrabCAD, and STEPTools CAD files, they must be downloaded directly from the GrabCAD and STEPTools websites [1-3,6]

## Directory Structure

The `evaluation-files` directory includes all relevant geometry files in various formats:

- Meshes: `.obj`, `.mtl`, `.glb`- CAD Parts: `.stp`, `.step`- Assemblies: `.obj`, `.step`, `.json`- Metadata: `.txt` part listings

## Dataset Composition

The test set is divided into three model types:

### Meshes [7]- Rubber Duck: segmented triangle mesh (`duck.obj`)- Utah Teapot: NURBS surface (`teapot.obj`)

### CAD Parts [6]

- `as1-ac-214.stp`- `io1-ac-214.stp`- `f1-db-214.stp`- `boxy_with_cylindricity.stp`

### Assemblies [1-5] [8]

- Airboat- Helicopter Rotor- Vex Robot Gripper- OLSK Large Laser V1- OLSK Small 3D Printer V1- Farmbot Genesis 1.5

Includes `.obj`/`.step` models and LLM-generated `.json` schemas.

## Purpose

This dataset supports quantitative and qualitative evaluation of hierarchicalanimation schema generation using LLMs. Each assembly varies in size,complexity, and part organization to test robustness and scalability.
