A BIM model viewer for the whole project team

Most of the people who need to look at a building model don't own the software that made it. The contractor pricing the job, the client approving a design, the engineer checking what the architect changed — they all receive IFC deliverables and need answers, not another license. This page turns any modern browser into that missing seat: drop the model on the canvas and walk it in 3D within seconds.

And because coordination is rarely about a single file, the scene is federated by design. Load the structural model on top of the architecture, add the MEP export, and study how the disciplines actually meet — the spatial tree keeps each model separate so you can flick one off, isolate a storey, or chase a duct through a wall. Everything is parsed locally by WebAssembly: no upload, no server copy, no queue, which is precisely what makes it usable on confidential projects.

Running a review in three steps

1. Load the discipline models. Drag each .ifc or .ifczip onto the canvas — they stack into one federated scene rather than replacing each other. Order is up to you; starting with architecture gives the rest context.
2. Interrogate the federation. Click an element for its attributes, property sets and quantities. Use the tree to isolate a level or a system, cut a section plane through the zone under discussion, and measure the clearances people are arguing about.
3. Capture the findings. Snapshot the views that matter for the coordination minutes, note the GlobalIds of problem elements, and — when a model looks suspect — send it through the IFC Validator for a written report instead of a hunch.

Why federate in a browser instead of a desktop suite?

Desktop coordination platforms earn their keep on automated clash rules and issue tracking — but most day-to-day questions are smaller than that. Does the new steel clash with the atrium? Which storey is this pump on? Did the consultant actually update their export? Answering those in a heavyweight suite means finding a workstation that has it installed, waiting for it to start, and converting files it doesn't like. Answering them here means opening a link.

Browser-side viewing also changes who gets to participate. A site manager in the field trailer, a subcontractor on a tablet, a client on their office laptop — anyone can inspect the current federation without touching the project's software stack. The models being reviewed never leave each reviewer's machine, so IT departments have nothing to sign off on either.

Part of a coordination workbench

Viewing is step one of a longer pipeline, and the rest of it lives on this site under the same rules — free, local, private. Audit a suspicious delivery with the IFC Validator, shrink a bloated export with the IFC Compressor, combine clean discipline files into one deliverable with IFC Merge, or pull every property into a spreadsheet with IFC to Excel. If you're new to the format itself, the pillar guide on what BIM actually is ties the whole workflow together.
