ifcquery is a new command-line tool for querying and inspecting IFC models. All output is JSON.
Subcommands:
summary — schema version, entity counts, project metadata
tree — full spatial hierarchy (Project → Site → Building → Storeys → Spaces → Elements)
info <id> — deep inspection of any entity by step ID (attributes, psets, placement matrix, type, material)
select <query> — filter elements using ifcopenshell selector syntax
relations <id> — relationships for an element; --traverse up walks to IfcProject
clash <id> — geometric intersection and clearance detection
validate — schema/constraint validation; --rules adds EXPRESS checks
schedule — work schedules with nested task trees
cost — cost schedules with nested cost item trees
schema <class> — IFC class documentation from the model's schema version
plot — SVG plan drawing
render — 3D geometry rendering
contexts — geometric representation contexts
materials — material assignments
Usage:
python3 -m ifcquery <file.ifc> <subcommand> [args]
