IFC properties explorer
Search any element by name, class or GlobalId and inspect its Psets, quantities and materials — without loading 3D, without uploading anything.

Check IFC data in seconds, not minutes
Most of the time you open an IFC file, you are not there to admire the geometry — you need an answer. Does this door have a fire rating? Which storey is that beam on? What is the GlobalId from the clash report actually pointing at? Loading a full 3D viewer for that is like starting a car to check what's in the glovebox. This explorer skips geometry entirely: it parses the IFC data, builds a search index in a background thread, and answers as you type — even on models with hundreds of thousands of entities.
Everything runs locally in your browser with WebAssembly. Your model is never uploaded — there is no server copy to worry about, which matters when the file belongs to a tender or sits under an NDA.
How it works
- Drop your IFC file. .ifc or .ifczip from Revit, ArchiCAD, Tekla or any IFC-compliant tool. The model is parsed and indexed once — you will see the schema, the element count and the time it took.
- Search. Type a name, a class (walls, doors, IfcBeam…) or paste a GlobalId. Combine terms, narrow to one class with the dropdown, and click any result to open its full record.
- Inspect and export. Attributes, every Pset, quantity sets, storey, type and material — copy one element as JSON, or download the whole filtered selection as CSV.
What AEC teams use this for
Resolving clash reports and issue lists. Coordination reports from Navisworks, Solibri or BCF workflows identify elements by GlobalId. Paste the id here and you instantly know what the element is, where it sits and who typed it — without waiting for a federated model to load.
Spot-checking deliveries against the BEP. Before accepting a model, filter by IfcDoor and confirm the FireRating is filled, or search a space name and verify its area quantity. For systematic checks across every element, export the filtered CSV and sort the blanks to the top.
Answering site and workshop questions. A contractor asks for the type and material of a specific assembly: search its mark or name, read the Pset, done. No BIM seat, no install, works on the laptop in the site office.
Understanding unfamiliar models. Received an IFC from another discipline? The class filter doubles as an inventory: see at a glance which classes the model contains and how many of each, then drill into any element's data.
Built for real project files
The explorer walks the IFC relation graph once — property sets, quantity sets, types, spatial containment and material associations — and turns it into an in-memory index. That single pass is what makes search instant afterwards: on a structural model with close to a million STEP entities, a query returns in a few milliseconds. Special characters in names and values (accents, umlauts, CJK — anything encoded as STEP escapes) are decoded correctly. And because parsing happens in a background worker, the page stays responsive throughout. If you need the data in a spreadsheet rather than on screen, the IFC to Excel converter exports the same properties as a multi-sheet workbook; to see the elements in context, the free IFC viewer opens the same file in 3D.
Frequently asked questions
Is it safe to inspect confidential IFC models here?
Yes. The explorer runs entirely in your browser using WebAssembly — your IFC file is never uploaded to any server. Close the tab and everything is gone, which makes it suitable for models covered by NDAs or tender confidentiality rules.
What can I search by?
By element name, GlobalId, IFC class, type name or storey — all at once, case-insensitive. Type several words to combine them (for example "door level 2"), and narrow the results to a single IFC class with the dropdown filter. Results update as you type.
What details do I see for each element?
The direct STEP attributes (Tag, ObjectType, PredefinedType…), every property set flattened into readable groups, quantity sets (areas, volumes, lengths), and the element's relations: the storey that contains it, its IfcTypeObject and its material or material layers. You can copy the whole record as JSON with one click.
How is this different from the 3D viewer?
The viewer loads geometry and renders the model, which takes time and memory. This tool skips geometry entirely and only reads the data, so even very large models are searchable in seconds — ideal when you need to check a property, not look at the building.
Can I export the results?
Yes. The Export CSV button downloads exactly what your current search and class filter match, with one column per property found in the selection. For a full multi-sheet workbook of the whole model, use the IFC to Excel converter instead.
Which IFC versions and sizes are supported?
IFC2x3, IFC4 and IFC4x3, plus compressed .ifczip files. There is no hard size limit — models up to roughly 300 MB work on a typical desktop machine, and because indexing runs in a background thread the page never freezes while it works.
