Full-cloud CAD pioneer Onshape’s most recent update introduces a new capability to edit parts within the context of assemblies. “This update is extremely significant,” remarked marketing director Darren Henry. “Yes, Onshape speeds up the design process by being full-cloud, but we’re also continuing to redefine how CAD is done.”
Designers want the ability to edit parts within the context of an assembly (top-down design) to ensure fit and function by defining relationships between components, Henry explains. “We believe that traditional approaches to top-down design have demoed well, but have not largely been successful when used in real-world design scenarios.” Continue reading →
Full-cloud CAD pioneer Onshape amped up the power and utility of its software with FeatureScript, a new programming language that lets users create new parametric features that look, feel and behave just like Onshape’s built-in features.
This is the same language used by Onshape itself to develop all of its software’s current features—Extrude, Fillet, Shell, Loft and the like. Now available as an open language, FeatureScript lets users create their own built-in parametric features in Onshape.
Under the open-source MIT License, Onshape is also sharing the FeatureScript source code for all of its own features, allowing customers to copy, modify or adapt them as they see fit. New features can be created, and existing features edited, in Onshape’s new Feature Studio, a user-friendly development environment with an editor, in-line help and documentation. Continue reading →
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.
