SolidWorks

SolidWorks is developed by a subsidiary of Dassault Systèmes, is known for parametric solid modeling, and is widely used in mechanical engineering and product design.

Fusion's personal edition is free, while SolidWorks is paid for by the company.

PuraMetric is closer to SolidWorks; according to developer MaleficentRelease61 on Reddit, it is written in Rust and JavaScript, took only about one month to develop, and used Claude Opus 5.5 to assist development.

PuraMetric lacks keyboard letter labels, and common SolidWorks shortcuts such as the S key, the spacebar, and right-click scroll wheel are completely nonfunctional.

PuraMetric lacks SolidWorks' ability to flexibly select contour regions for extrusion or cut, so users can only go back into the sketch to delete lines.

An engineer who uses SolidWorks about six hours a day said that when faced with the question "would you be willing to give up your SolidWorks license," the answer is "absolutely not."

Users only need to describe the shape and dimension requirements of a part, and the AI can plan the modeling steps, create the 3D model, and further handle assembly, engineering drawing generation, and file export.

The Agent checks whether the tool ran successfully and further verifies the model dimensions, rebuild status, and the validity of the exported files.

Rebuild status is the direct signal in SolidWorks for judging whether a model is healthy; if a feature fails due to geometric conflicts, lost references, or over-defined constraints, the model will show a rebuild error or warning.

SolidWorks provides a COM interface and API that allow external programs to create sketches, add features, read mass properties, and export files, covering most of the actions of manual operation.

When using the project, it is recommended to start with simple parts, and to pay attention to SolidWorks version compatibility and the permission configuration that the Agent may require during operation.

The project lets an AI Agent directly call the real SolidWorks software to perform modeling tasks.

AutoCAD is Autodesk's market-leading product, while SolidWorks and CATIA are Dassault's market-leading products.

Parametric modeling is the core paradigm of modern CAD, and tools such as Fusion 360 and SolidWorks are based on it, suitable for mechanical part design that requires repeated iteration.

API hallucination refers to the phenomenon in which large language models generate nonexistent function names or APIs from the wrong version, and it is common in frequently iterating SDKs such as SolidWorks, AutoCAD, Unity, and Unreal.

The founding team of Onshape (many of whom came from the original SolidWorks development team) began building a fully cloud-based CAD platform in 2012, introducing version control and real-time multi-user collaboration to the CAD field.
