Start with the task
Two source-based selection pilots, checked 2026-09-11. We inspected publisher descriptions and license statements—not downloaded datasets, trained models or validated IFC files.
Access is not permission to reuse. Dataset annotations, source drawings, software and model weights can have different rights. The comparisons do not add records to the directory count.
Choose floor-plan data by prediction task
For raster segmentation, investigate CubiCasa5K. For vector-line symbol spotting, investigate FloorPlanCAD. Neither inspected license establishes unrestricted commercial use. Model architecture, annotation conversion, split leakage and drawing rights require their own checks.
On narrow screens, scroll the comparison sideways.

Choose IFC samples by test purpose
Start with a small version-matched buildingSMART example and independently validate it. Use the community collection to broaden positive and negative cases only after recording the expected outcome per file. These are sample libraries, not interchangeable machine-learning benchmarks.

Community Sample & Test Files: citation
Citation: Original contributor, selected file, export date and repository commit; retain its accompanying README.
Before use: save the exact version, publisher license and attribution; inspect file-specific restrictions; then test a small authorized sample. An unknown permission or validation result stays unknown.
Access labels describe availability, not permission to reuse. Recorded license labels may be incomplete or stale. Check the publisher's current license and any third-party restrictions before commercial use, redistribution, or model training. DataDrivenAEC does not license the linked resources.
