Cortona3D Viewer allows you to view interactive 3D/2D product catalogs, work instructions, maintenance guides and manuals created with Cortona3D RapidAuthor. Many equipment manufacturers are now providing richer content in their technical documentation and information.

Interactive 3D provides a more intuitive way to communicate complex maintenance or assembly tasks. 3D parts catalogs make it easier to identify and order the correct parts. As a classroom aid or for “just-in-time” training the app provides an effective way to teach mechanical skills. It can even be used as a sales aid to demonstrate new product features and functions.

The Cortona3D Viewer on iOS is the perfect complement to the RapidAuthor tools. Using CAD and bill of materials data sourced from Engineering, RapidAuthor allows you to generate the complete technical document including text, 2D and 3D graphics.

If your company does not yet use Cortona3D RapidAuthor you can still install Cortona3D Viewer and view the sample content. As you will see there is support for both 3D and legacy 2D graphics.

Not a browser plugin

It was not made clear, at least to me, that this is not a browser plugin like the windows version. Unfortunately, that is what I need as the manufacturer (Winnebago) does not make the parts catalog available for download. I am forced to rate this APP but I can’t really do it fairly as it does not do what I was hoping it would but maybe it works well for other uses.
