## Overview

gNucleus AI targets engineering teams that want generative AI inside the CAD and simulation loop. Its core offering is a family of multimodal models trained on engineering data that can turn a text description, a sketch, a photo, or a legacy drawing (PDF/DXF) into editable, feature-based parametric CAD. Outputs land in native formats like CATIA, SolidWorks, and FreeCAD, plus neutral formats such as STEP and STL, so generated geometry fits existing workflows rather than replacing them.

Beyond single parts, the platform supports both top-down and bottom-up assembly generation with auto-created components and mating constraints. A suite of engineering agents extends the workflow: a Design Spec agent drafts parameters and constraints, a CAD agent produces parts and assemblies, a Simulation agent runs multi-physics workflows in tools like Ansys and Altair, and an Optimization agent interprets results and suggests improvements.

For enterprises, gNucleus offers proprietary model training and serving on your own engineering data, LoRA fine-tuning, managed or private cloud deployment, and professional data labeling and evaluation services for CAD and simulation datasets. It cites applications across automotive, robotics, and consumer electronics.

## Pricing & Plans

A free trial grants 150 credits to try CAD-AI generation, with bonus credits available for following the company on social channels. Ongoing plans are quote-based and arranged by contacting the team or booking a demo.

## Key Features & Capabilities

- **Text and image to CAD:** Generate feature-based, parametric CAD parts from text descriptions, PDFs, DXFs, and PNG/JPG images in native and neutral formats.
- **Assembly generation:** Create top-down or bottom-up assemblies from text, with components and mating constraints generated automatically.
- **Engineering AI agent suite:** Agents for design specs, CAD generation, multi-physics simulation via Ansys/Altair, and design optimization.
- **Enterprise model training and deployment:** Train and serve proprietary models on your engineering data with LoRA fine-tuning and multi-cloud, private, or managed deployment.
- **CAD and simulation data services:** Professional data labeling and evaluation services to train and validate AI models on engineering datasets.

## Primary Use Cases

- **Digitizing legacy drawings (Mechanical design engineer):** Turn PDFs, DXFs, and scanned drawings into editable 2D sketches and 3D solid models instead of remodeling from scratch.
- **Accelerating assembly design (CAD team lead):** Generate parametric assemblies with mating constraints to shorten iteration cycles on complex products.
- **Multiphysics workflow automation (Simulation engineer):** Run simulation workflows in Ansys and Altair through agents that also interpret results and suggest optimizations.
- **Private, domain-tuned models (Manufacturing enterprise):** Fine-tune generative models on internal engineering data and deploy them in a private or managed cloud.

## Strengths

- Generates editable, feature-based parametric CAD rather than mesh-only output
- Native support for CATIA, SolidWorks, and FreeCAD plus STEP/STL interchange
- Covers the wider workflow with agents for specs, simulation, and optimization
- Enterprise path with fine-tuning, private cloud, and data labeling

## Limitations

- Ongoing pricing requires a sales conversation rather than transparent self-serve tiers
- Enterprise-grade capabilities imply a steeper setup and adoption curve
- Best value depends on having substantial engineering data to train on
