Reference manual for BuildBrain CLI tools (ifc_extract.py and pdf_extract.py). Shows all commands, flags, output formats, and type shorthands. Use this as a reference when working with IFC or PDF data.
Compare IFC model data against PDF drawing schedules. Reads saved extraction data from output/, identifies count mismatches, missing properties, and conflicting values. Generates Markdown discrepancy report with PASS/WARN/INFO flags.
Extract schedules, text, and tables from PDF construction drawings. Can search for specific terms to find relevant pages. Results saved to output/ for cross-validation.
Generate formatted construction deliverables — QTO tables, element schedules, material takeoffs, compliance checklists. Reads extracted data from output/, uses quantities command for aggregates. Formats per Australian construction conventions.
Scan IFC and PDF files to create a project inventory. Shows element counts, schedule locations, and data quality issues. Use when starting work on a new project or wanting an overview.

Extract building element data from IFC models. For full CLI command syntax, flags, type shorthands, and natural language translation tables, see /cli-tools.
If no file path provided:
ls data/*.ifc 2>/dev/null
Multiple files → ask user. No files → tell user to place IFC file in data/.
Scripts are at skills/cli-tools/scripts/ifc_extract.py. Always include --save.
python skills/cli-tools/scripts/ifc_extract.py <file.ifc> <command> [args] --save
Use /cli-tools to look up the correct command for the user's request. Common patterns:
| User says | Command |
|---|---|
| "show me all doors" | list door --save |
| "fire-rated doors" | query door --property Pset_DoorCommon.FireRating --not-null --save |
| "external walls" | query wall --property Pset_WallCommon.IsExternal --value true --save |
| "how many windows per level" | quantities window --group-by storey --save |
| "what's in this model" | summary --save |
| "data quality check" | validate --save |
quantities commandlist door: "Filter for fire-rated doors? Check quantities per level?"summary: "Which element type to explore?"/pdf-extract to find the matching PDF schedule?"quantities for counts, areas, volumes.--save for downstream use by /cross-validate and /report.
