Check out this page, where you can view a Navisworks model over the web via an ActiveX control.
No installation needed, very cool!
Just select the sample model from the drop down list and use the buttons on the left to change the current navigation mode.
The page also includes two point clouds scans that our friends in the U.K. have shared with us. Please note that the loading of the point cloud takes a wee bit longer.
Please share any feedback you may have.
