CAD Exchanger Web Toolkit is a set of JavaScript libraries to visualize, explore and analyze 3D CAD models. Unlike Autodesk Forge, Web Toolkit can be used to develop web applications running entirely on premise (i.e. inside a corporate network) without exposing any confidential data outside of the company.
In order to display any 3D file with the help of Web Toolkit, the contents must be first prepared by converting the original 3D file into a specific format called CDXWEB or CDXBIMWEB. Both of them are highly-compressed binary formats that allows efficient data transfer over networks to provide excellent application responsiveness and UX.
