An illuminating blog post by Onshape engineering team member Ilya Baran reveals some fundamentals of how the new cloud-native CAD system works: “We are careful to distinguish several types of data: the User Interface (UI) state—e.g., selection, camera view, current tab; the Part Studio definition—e.g., feature list, part names and colors, import data; [and] Regeneration results—the ‘b-rep’ (bodies, faces, edges, etc.), triangles for display, regen errors.”
How do these data types differ? “The UI state generally doesn’t persist (except for things like named views),” Baran writes. “The regeneration results are cached, but they can always be rebuilt from the definition. The Part Studio definition is what we store in the database and that is where collaborative editing happens.”
Then Baran explains something that begins to suggest why we believe Onshape is not only a breakthrough in CAD, but also poised to disrupt the established paradigm for PLM platforms. Continue reading →
SIMSOLID Corporation launched SIMSOLID, a new structural analysis software product developed specifically for design engineers that works directly on fully featured CAD assemblies and complex part geometry and does not use a mesh. Founded by industry veterans Ken Welch, CEO, and Victor Apanovitch, President and CTO, SIMSOLID’s novel approach is intended to eliminate the two most time-consuming and expertise-intensive tasks of traditional FEA—geometry simplification and meshing. The company says SIMSOLID can analyze complex parts and large assemblies not practical with traditional FEA and do it efficiently on a desktop-class computer. Solution accuracy is controlled using what the company describes as a unique multi-pass adaptive analysis; adaptivity can be defined on a global or part-local basis and is always active. SIMSOLID contains a direct data integration with Onshape CAD documents and is available in the new Onshape App Store as well as directly from SIMSOLID.
DATADVANCE presented pSeven Cloud, the first full-cloud design space exploration platform, at the NAFEMS European SPDM Conference held Dec. 2-3 in Munich. pSeven Cloud is part of the emerging new generation of full-cloud design and simulation software tools such as Onshape, SimScale and Sim4Design. DATADVANCE CEO Sergey Morozov showed how pSeven Cloud complements those design and simulation tools by adding the critical capability of design space exploration, essential for implementing simulation-driven design methodology. Based on DATADVANCE’s efficient, production-proven data analysis and optimization algorithms, pSeven Cloud features the company’s SmartSelection™ metaheuristics that automatically selects the most appropriate and efficient analysis or optimization method based on the user’s description of the problem.

Onshape went public with avidly anticipated details of its full-cloud 3D CAD system that lets everyone on a design team work together using any web browser, phone or tablet, and has data management and collaboration built in at its core. While this groundbreaking technological approach has generated high excitement in the run-up to today’s unveiling, Onshape’s pricing model is an equally disruptive component of its strategy to make professional-grade CAD radically more accessible than ever before.
