OnShape is a brand new creation from the original team that built out SolidWorks. This is sort of a combination of the concepts that makes Google Docs great mated with a world class solids modeling package. We can finally do all of these things in the browser and run it on something as low power as a cell phone.
With a tool like this and the proliferation of inexpensive 3D printers, it’s hard to see this as anything except a major game changer. Collaborating on the same 3D document in real time is something nobody’s done before. The most welcome thing to me is branching and merging within a solids file. Merging changes in larger 3D packages has always been a chore and collaboration on a document like this could not exist without seamless merges.
