Onshape is a computer-aided design (CAD) software system, delivered over the Internet via a software as a service (SAAS) model. It makes extensive use of cloud computing, with compute-intensive processing and rendering performed on Internet-based servers, and users are able to interact with the system via a web browser or the iOS and Android apps.[1] As a SAAS system, Onshape upgrades are released directly to the web interface, and the software does not require maintenance work from the user.[2]
