The BLDG360 site was created by Autodesk partner, http://www.cadcompany.nl/" rel="noopener noreferrer - CAD & Company who offers its construction, civil engineering, and manufacturing customers a better workflow to improve quality and reduce time. They do this by selling Autodesk software subscriptions, training their customers, providing services, and developing software with technologies such as Autodesk Forge.

CAD & Company got started with Forge by using the Viewer to create BLDNG360. They soon discovered that the models did not have the quality they wanted. They analyzed the problem and came up with two ways to improve our building models:

1. To provide better building components, they used the Viewer to create a platform to host Autodesk Revit families of high-quality building elements — a new public library, BuildingContent.

2. To give their users a tool to check their building models, they used the Viewer and Model Derivative API to create a smart logbook that eliminates lists, spreadsheets, endless emails, cut and paste, and countless phone calls — Collaborea.

Collaborea consists of three elements:

1. Collaborea for Autodesk NavisWorks — a rules-based model checker that "automagically" checks building models for clashes and data quality
2. BLDNG360 — a site to communicate modeling issues to the extended team so designers and project leaders can instantly and easily see what needs to be fixed
3. Colaborea for Revit — a way for designers to download issues from BLDNG360 and adjust their models

I tried BLDNG360 for myself. The site allowed me to select a building design and explore it in detail. I could pan, zoom, and orbit. For example, the site includes a model of the http://www.amsterdamarena.nl/stadium-surroundings/history.htm" rel="noopener noreferrer - Amsterdam Arena :

This all happens using just my browser, Chrome in my case, without the need to download and install any software — not even a plug-in. This is because the BLDG360 site uses the Model Derivate API to convert this Autodesk Revit model into a simple vector format (SVF) file [referenced by a Universal Resource Name (URN)] that can be viewed natively in the browser.

In addition to simple 3D navigation, metadata about the arena is also displayed and/or computed. For example, I used the first-person mode to walk along the field and measure the distance between exits:

This is possible because CAD & Company are also using the Model Derivative API to export model elements for calculations, specifications, and for planning (i.e., ERP systems), enabling their customers to use the building model data in other functions without a lot of IT effort. They believe their use of Forge brought them into a position where they could talk to their customers about their primary processes.
