Open a building model.

Choose an IFC, RVT, RFA or DWG file, or a whole project folder, from your computer. Or drag either onto this page: a dragged folder opens without a permission prompt. It opens here, in your browser; nothing is uploaded.

• IFC

  The full model in 3D. Orbit it, turn storeys on and off, and click any element to see its properties and quantities. Change names, tags and property values, then save a new IFC; your original stays as it was.

• RVT and RFA

  A file card: the release it was saved in, project information, the preview picture and linked files. The 3D model inside an RVT is in an undocumented format, so to see it in 3D, export IFC from the app that made it (File, Export, IFC) and open the .ifc here.

• DWG and DXF

  The drawing in 2D: model space and every sheet, pan and zoom, layers on and off, with live coordinates. Print view shows it black on white with its line weights. Linked drawings and title-block pictures are found in the open folder. AutoCAD 2000 to 2018 formats.

• A folder

  Every model in a project folder at once: numbered backups grouped with their model, linked files checked against the folder, and incomplete files flagged. Only the few kilobytes each card needs are read, so a network drive is fine.
