Cloud CAD
Cloud CAD (also "CAD cloud") refers to computer-aided design software that runs in the cloud rather than installed locally on a workstation — with all geometry, assemblies, and version history stored server-side and accessed via a web browser or thin client. The defining architectural difference between cloud CAD and traditional desktop CAD is data location: in desktop CAD (SOLIDWORKS, Creo, CATIA), the CAD files live on local drives or a file server and are locked when checked out; in cloud CAD (Onshape, Fusion 360, Shapr3D), the model lives in a cloud database and is the single source of truth — multiple users can view or work on different components simultaneously without file-locking conflicts. Cloud CAD platforms provide native version control (every save is a revision, branching and merging are built in), real-time collaboration (concurrent editing with live cursors), platform-agnostic access (any OS, any browser), and no local installation or IT infrastructure. The three main cloud CAD platforms differ by target user: Onshape targets professional mechanical engineers at teams and enterprises (PTC-backed, strongest PDM integration); Fusion 360 targets product design and manufacturing programs that need integrated CAD/CAM/simulation; Shapr3D targets concept design with iPad/Apple Pencil-first UX and desktop fallback.
In context
A 12-person hardware startup designs a medical device entirely in Onshape: mechanical engineers in Boston work on the enclosure while the firmware team in London updates connector cutouts simultaneously — no file conflicts, no email attachments, and the full revision history is searchable the day before FDA audit. A contract manufacturer onboards a new OEM customer by sharing a read-only Onshape workspace, eliminating the ITAR-compliant file transfer process that previously required signed NDAs, encrypted USB drives, and a two-week lead time.
Why it matters
Cloud CAD eliminated the infrastructure overhead that made CAD inaccessible for distributed teams, startups, and small manufacturers. Before cloud CAD, a team of ten needed a file server, VPN access, an IT administrator, and a PDM system just to avoid overwriting each other's work. Cloud CAD replaced all of that with a login. For product development startups and contract manufacturers working with multiple OEM clients, cloud CAD's architecture is not a feature compromise — it is a deployment and collaboration advantage over desktop CAD with its inherited file-server complexity. The limitation is performance on very large assemblies (100,000+ components) and legacy data compatibility: organizations with years of legacy SOLIDWORKS or Creo files face significant migration effort, and cloud CAD's file import fidelity for complex parametric assemblies remains imperfect.
