Your 3D model as one self-contained HTML file

Revit, IFC, DWG, Navisworks and point clouds become a single HTML viewer: nothing to install, nothing to host, works offline, small enough to email. The person you send it to opens it in a browser, with no login, and can measure, section, walk through and mark it up.

Free for IFC, DXF and scans, no accountEstimate shown before anything is chargedThe file is yours, for good

Works with

Drop one file, or several: an IFC with a scan and a DXF align into one viewer. Revit, DWG and Navisworks are converted through Autodesk's cloud and need tokens; the rest are free to try.

How it works

Drop the file

On the Create page, from a laptop or a phone. The estimate appears before you press anything.

Wait about a minute

You are never charged above the estimate, and a creation that fails costs nothing.

Send the file

One .html, usually a few megabytes. Email it, drop it in the project folder, keep it. It works with the internet off.

What is inside the file

The whole viewer travels with the model: no library is fetched when it opens, and nothing is sent back.

  • Every element selectable, with its category, type and parameters
  • Measuring with snapping: distances, angles, diameters
  • Sections, levels one at a time, and a plan minimap
  • Walk-through at eye height; saved views to send people to
  • Pinned comments and markups, exported as a report or spreadsheet
  • Freehand sketches and kept dimensions (Studio pack, Team and up)
  • Your own logo in the corner (Office pack, Pro and up)
  • Six languages; opens on a phone, a tablet or a laptop

The free tier makes the same file with a watermark and measuring and the review panel switched off, so you can judge it before paying anything.

See one

Real viewers made by the service, with the model each came from in its guide.

Udraft Bridges Example

HTML file created from original .rvt with linked .dwg, .rvt, .ifc, nwc and point cloud.

Bridge One IFC

3D model bridge HTML file created from .ifc - 3 spans with planks, on concrete piles.

Survey Example

HTML file created from a .dwg file.

Bridges Navisworks

HTML file created from .NWD file.

A file, not a link

Hosted viewers give a client a link, a login and a server the model lives on. A file does none of that.

Sending to a client

No software to install, no account to create, no link that expires when the project account does. Double-click and it opens.

  • Works on a laptop, a tablet or a phone
  • Comments and markups come back as a report

Under NDA, or on site

With the Revit add-in the model never leaves your PC: only a small token check goes out. On site, the file works with no connection at all.

About a minute. Free for IFC, DXF and point clouds with no account; Revit, DWG and Navisworks with tokens from A$17, or a membership with the Revit add-in.
