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
