One model, one file: a guide for every format
One self-contained HTML file: nothing to install, nothing to host, works offline, small enough to email. Each guide says what the format brings, what it costs, and how to send the result to someone who has nothing installed — with a real example where there is one.

Revit viewer: share an RVT model as one HTML file
Upload the .rvt, or export from inside Revit with the add-in so the model never leaves your PC. Either way the result is one HTML file with the 3D view, element properties, measuring, sections and markups built in.
GuideIFC viewer online, free: one HTML file, no install
IFC is the format everyone can export and nobody can open without another install. Drop it here and get one HTML file back that anyone can open in a browser.
GuideDWG viewer: send a drawing as an interactive 3D file
The person you send a drawing to should not need AutoCAD to look at it. A DXF converts free; a DWG is converted through Autodesk's cloud and needs tokens.
GuideNavisworks viewer: share a coordination model as one HTML file
Publish from inside Navisworks Manage or Simulate with the add-in, so the model never leaves your PC, or upload an .nwc. Either way the result is one HTML file with the federated model, element properties, measuring, sections and markups built in, for people who have no Navisworks at all.
GuidePoint cloud viewer: share a scan as one HTML file
A surveyor's scan should not need the surveyor's software to look at. Drop the .e57 or .las here and get one HTML file back that opens on any laptop, on site or in a meeting, with the internet off.
GuideEmail a 3D model to a client, no software, no login
Cloud viewers give a client a link, a login and a viewer they have to learn, and the link stops working when the project account does. A file does none of that.
GuideConvert RVT to an HTML viewer
Not a screenshot, not a link: the Revit model itself as one HTML file, geometry and properties included.
ComparisonAutodesk Viewer alternative: an offline file instead of a cloud link
Hosted viewers and Udraft 3D solve the same problem in opposite ways. This page sets out the difference plainly so you can pick the right one for the job.

About a minute. Open formats are free to try with no account; Revit, DWG and Navisworks need tokens.
