Cosmon (Argus)
Argus is an AI agent for CAD, simulation, and PLM work that executes tasks natively inside the tools teams already use, from drawing creation to simulation setup and design validation.
Summary rewritten from the vendor site because the catalog version did not match it.
What it does and how it connects
Argus brings autonomous product development to hardware teams across CAD, simulation, and PLM workflows, with a plain-language interface and no scripting or macros. It can be trained on a team's standards, templates, and conventions so what it produces matches how the team already works.
Argus executes tasks natively inside the tools teams use, working directly from the engineering model, including geometry, feature tree, and constraints, with no export and no separate report. The homepage lists multi-step tasks it handles, such as a full external-aero CFD study, a tolerance stack-up, and work instructions built and summarized for sign-off.
The vendor states Argus was given real engineering tasks in SolidWorks, NX, Creo, and CATIA and every result checked against expert-set answers, with every check, time, and cost published. Deployment is in the cloud or fully on-premise with the customer's own keys, SOC 2 compliant, with zero data retention and data never used to train models.
Alternatives
Compare side by side- Bananaz (Design Agent)
A Design Agent that works natively inside CAD and PDM from plain-language requests to release-ready packages, rather than Argus across CAD, simulation, and PLM.
- Bench
AI agents that generate and execute engineering design workflows across a team's existing CAD, CAE, and PLM tools, rather than Argus running tasks natively in CAD, simulation, and PLM.
- MecAgent
A commercial desktop copilot that acts inside a live SolidWorks session, rather than an agent spanning CAD, simulation, and PLM.
- Adam CAD
An AI copilot that works inside connected CAD and PLM from chat in Slack or email, rather than an agent for CAD, simulation, and PLM tasks.
- Backflip AI
Rebuilds scans, photos, and drawings as parametric CAD in Fusion, rather than executing CAD, simulation, and PLM tasks.
Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- A shipped SolidWorks agent skill called interference-check API methods that do not exist (InterferenceDetection, GetInterference(index), GetComponents) and called Done() before computing, so its core validation step could never complete on a real machine. The check silently never ran.Error Index
- On SolidWorks 2016, the set_dimension tool reports success for a sketch dimension change the sketch cannot solve. The dimension stores the new value while the solver rejects it, the geometry does not move, the sketch is left no_solution, and check_errors reports nothing. Measured probes showed the mass and every segment unchanged against the ok:true answer.Error Index
- A SolidWorks MCP bridge returned success JSON and even a normal-looking PDF export while the live document was wrong: a sketch asked for the Right plane silently landed on Front, and a macro call reported success=False with zero errors while never running. Only visual inspection inside SolidWorks itself revealed it.Error Index
- Saving an assembly can trigger rebuilds that break mates and randomly alter mate dimensions.Error Index
