Free IFC viewer for Windows

BIM Explorer

Open any IFC model and explore it - the model tree, every element's properties, display modes, sections, measuring and search. Free, offline, and your models never leave your PC. Need quantities? The optional one-off BIM Explorer Pro upgrade adds quantity takeoff, a BOQ linked to the model, revision compare and BCF issue review.

Frequently asked questions

Is BIM Explorer free?

Yes. Viewing IFC models is free and always will be - the 3D viewer, model tree, properties, display modes, sections, measuring, search and the model library. BIM Explorer Pro is an optional one-off upgrade (£19.99 through the Microsoft Store) for quantity takeoff, a BOQ linked to the model, revision compare, BCF issue review and exports. No subscription and no account.

What files does it open?

IFC models (.ifc), including large ones - BIM Explorer prepares big files in stages and shows its progress. Drag a file onto the window or browse for it, or load the built-in sample building to look around first.

Do my models leave my PC?

No. Models are opened and kept on your PC, in BIM Explorer's own model library. Nothing is uploaded anywhere.

Do I need an account?

No. BIM Explorer opens straight to the viewer with no sign-in. You can register your copy for update notices, but it's optional.

What's the difference between BIM Explorer and Forma?

BIM Explorer is now built on the same engine as Metre2 Forma. The viewer is free, and Forma's quantity and commercial tools come with BIM Explorer Pro.
