CADWOLF is a web based collaborative engineering platform. Users create web pages and then add text, equations, plots, free body diagrams, loops, and a number of other items. All of this is done interactively within a web browser with no coding and nothing to download or install. Equations in documents can be shared with other documents and also linked to the Onshape CAD system. This means that when a requirement or measurement changes in one part, all connected part documents update automatically and those updates are then automatically reflected in the CAD models. Documentation, mathematics, and CAD models never need to be manually updated and can never get out of sync. Our part tree system provides a mechanism for users to create a part numbering scheme and then create parts that each have a document where the design of that part is carried out. This provides not only a mechanism to organize the design of large structures, but also a way to see the real time status of items like Weight, mass, and volume from both the design documentation as well as the CAD models. Workflows then pull all of this together by providing a place to collaborate through the process of engineering a large structure.
