# CAD-1K Open v2 - 1,018.1229 Hours

509 end-to-end, single-display Windows CAD task recordings across seven CAD software families.

Each task contains:

- `task_desc.json` - task prompt, application, reference-input paths, and expected deliverables
- `input_files/` - reference inputs named `input.ext` or `input_N.ext`
- `output_files/` - submitted CAD deliverables and supplemental outputs named `output.ext` or `output_N.ext`
- `rubrics.json` - task-specific evaluation criteria
- `task_overview.pdf` - review document combining the task, rubrics, and current visual references
- `clip.mp4` - screen recording video
- `frame_events.json` - events synchronized to video frames
- `metadata.json` - duration, frame, event, category, and platform metadata
- `narration.json` - frame-level task narration

| Windows | 509 | 1,018.1229 | 100.0% |

### Artifact Coverage

Every task has all seven required root files, at least one reference input, and at least one submitted output.

| Artifact group | Files | Tasks covered |
| --- | ---: | ---: |
| Root task files | 3,563 | 509 |
| `input_files/` | 545 | 509 |
| `output_files/` | 1,347 | 509 |

### Reference Input Formats

| Format | Files |
| --- | ---: |
| PDF | 339 |
| JPEG (`.jpeg`) | 102 |
| AutoCAD (`.dwg`) | 47 |
| PNG | 38 |
| SketchUp (`.skp`) | 8 |
| JPG (`.jpg`) | 4 |
| Revit (`.rvt`) | 4 |
| SOLIDWORKS assembly (`.sldasm`) | 2 |
| WebP | 1 |

AutoCAD visual inputs are derived from the human gold drawings. Blank-start tasks expose the derived visual reference, while edit-existing tasks retain the supplied native starting file alongside the visual reference. The current `task_overview.pdf` files were regenerated from these inputs.

### Submitted Output Formats

| Format | Files |
| --- | ---: |
| PDF | 525 |
| AutoCAD (`.dwg`) | 317 |
| SOLIDWORKS part (`.sldprt`) | 149 |
| Log (`.log`) | 146 |
| PNG | 39 |
| SketchUp (`.skp`) | 35 |
| Revit (`.rvt`) | 24 |
| Siemens NX part (`.prt`) | 20 |
| SOLIDWORKS drawing (`.slddrw`) | 16 |
