IfcQuery
========
IfcQuery is a CLI tool for querying and inspecting IFC building models. It
provides read-only subcommands for common inspection tasks, all outputting JSON
so results can be piped into other tools.
Subcommands:
- **summary** — schema version, entity counts, project metadata
- **tree** — full spatial hierarchy (IfcProject → Site → Building → Storeys → Spaces → Elements)
- **info** — deep inspection of any entity by step ID (attributes, property sets, placement matrix, type, material)
- **select** — filter elements by IFC class using the IfcOpenShell selector syntax
- **relations** — relationships for an element; use ``--traverse up`` to walk the hierarchy to IfcProject
- **clash** — geometric intersection and clearance checks; requires the IfcOpenShell C++ geometry bindings
- **validate** — schema and constraint validation; add ``--rules`` for a full EXPRESS check
- **schedule** — work schedules with nested task trees
- **cost** — cost schedules with nested cost item trees
- **schema** — IFC class documentation using the loaded model's schema version
- **contexts** — geometric representation contexts
- **materials** — material definitions (IfcMaterial, layer sets, constituent sets, profile sets)
- **plot** — generate a drawing (SVG or PNG) using ``ifcopenshell.draw``; PNG output requires ``cairosvg``
- **render** — off-screen 3D render to a PNG image; requires ``pyvista`` and the IfcOpenShell C++ geometry bindings
All subcommands accept ``--format json|text`` to control output (default: ``json``).
Installation
------------
::
pip install ifcquery
For PNG output from ``plot``, also install ``cairosvg``::
pip install cairosvg
For 3D rendering with ``render``, also install ``pyvista``::
pip install pyvista
Or install from source:
1. :doc:`Install IfcOpenShell <ifcopenshell-python/installation>`
2. `Clone the IfcOpenShell repository <https://github.com/IfcOpenShell/IfcOpenShell>`_.
3. ``cd /path/to/IfcOpenShell/src/ifcquery``
4. ``pip install .``
