1.) Once you have your Revit model published to a 3D DWF, go to the Autodesk Seek website and select a family to view 3D in the Autodesk Seek Viewer
2.) If you haven't been to the Autodesk Seek website before, download and install the plug-in - save the plug-in, you'll want it later.
3.) Once installed and viewing the family, right-click and select
4.) Sift through the code (there's not a whole lot to it) and replace the source location of the Autodesk Seek family with the location of your DWF. There are additional parameters for background color and gradient, initial camera view parameters such as pitch, roll, elevation and zoom factor you can play with.
5.) Save the file with the .html file extension
6.) Open the .html file in Internet Explorer and Voila! You now can view your Revit model in a simple, lightweight, easy to use viewer on the web with all the same amenities (render modes, interactive splicer, etc) as the Autodesk Seek website.
Anyone who has ever been to the Autodesk Seek website and installed the Autodesk Seek viewer plugin can view these right away; and what about the rest who have not? Well, you'll have to put a link on your website so they can install it on there machines; that's why I suggested to save the plug-in when downloading it from Autodesk. :D
This is a great tool for marketing a large multi-unit development where you could have an online Site Plan of the development and graphically link to an interactive 3D model of each unit. And it's simple enough that Joe-Shmo off the street can use it; a lot easier to use and less involved than Design Review.
