What is gNucleus AI?
gNucleus AI is an end-to-end engineering AI platform. Its generative engineering models and AI agents generate feature-based, parametric CAD parts and assemblies from text, images or DXF drawings, and support design specification, simulation and optimization workflows; enterprises can also get CAD and simulation data labeling, proprietary model training and managed or private cloud deployment.

Key features of gNucleus AI
gNucleus AI offers a Design Spec Agent, a CAD Agent that generates parts and assemblies from text, images and DXF, a Simulation Agent that works with CAE tools including Ansys and Altair, and an Optimization Agent.
Text-to-CAD parts
Generate feature-based, parametric CAD parts from text in native SolidWorks, Catia or FreeCAD formats and in STEP or STL.
Assemblies from text
Generate top-down and bottom-up assemblies with auto-generated component and mating constraints.
Image-To-CAD
Turn PDFs, DXFs and PNG or JPG images into editable 2D sketches and 3D solid models.
Engineering AI agents
Design Spec, CAD, Simulation and Optimization agents cover the engineering workflow, including multi-physics simulation with tools such as Ansys and Altair.

Frequently asked questions about gNucleus AI
It is an end-to-end engineering AI platform that generates CAD parts and assemblies and automates design, simulation and optimization tasks with AI agents.
Native SolidWorks, Catia and FreeCAD formats, plus universal formats like STEP and STL.
Yes. The Basic plan is free with 100 credits per month and text-to-CAD.
CAD and simulation data labeling and augmentation, proprietary CAD and physics AI training, and managed AI serving; a demo can be booked.
Yes. gNucleus provides direct fine-tuning and LoRA fine-tuning for customers.
It depends on your specific needs and how you plan to use the tool. The official website and documentation are the best sources for the latest details.
Conclusion
Text descriptions become feature-based, parametric CAD parts in native SolidWorks, Catia or FreeCAD formats or as STEP and STL, and assemblies can be generated the same way with their mating constraints. Old PDF, DXF or image drawings can be turned into editable 2D sketches and 3D solid models. Separate agents handle design specifications, multi-physics simulation with tools such as Ansys and Altair, and optimization.
gNucleus aims at automotive, robotics and consumer electronics work, with enterprise services that cover CAD and simulation data labeling, proprietary model training and private cloud deployment. Individual engineers and small teams start on a free Basic plan, but credits cap monthly usage and assemblies or image-to-CAD need a paid plan.
