| # 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. |
