TLDR: Autodesk has unveiled Neural CAD, a groundbreaking suite of 3D generative AI foundation models, at AU 2025. These models are set to integrate into Autodesk’s Fusion and Forma platforms, promising to redefine traditional CAD geometry creation and automate a significant portion of design workflows, enabling faster iteration and seamless transitions from conceptual to detailed design.
At its annual AU 2025 conference, Autodesk announced a significant leap in design technology with the introduction of Neural CAD, a new category of 3D generative AI foundation models. These innovative models are slated for integration into two of Autodesk’s flagship products: Fusion, for product geometry, and Forma, for architectural and building design. The company asserts that Neural CAD will fundamentally ‘reimagine the traditional software engines that create CAD geometry’ and automate ’80 to 90% of what you [designers] typically do,’ marking a transformative shift in the design and manufacturing industries.
Neural CAD is designed to enable designers to produce high-quality CAD geometry using various inputs, including natural language prompts, sketches, or imagery. This capability is expected to significantly accelerate the early stages of design, fostering rapid and iterative exploration of ideas, which research has shown to enhance project metrics such as cost-efficiency, sustainability, and overall suitability.
For architects utilizing Autodesk Forma, Neural CAD for buildings will facilitate a fluid transition between initial design concepts and more intricate building layouts and systems. The technology boasts the ability to autocomplete repetitive design aspects. As one expert, Haley, noted, ‘If I was to change the shape of a building, it can instantly recompute all the internal walls.’ This extends to instantly recomputing columns, platforms, cores, and grid lines, thereby streamlining the creation of structural drawings.
Similarly, designers working with Autodesk Fusion will leverage Neural CAD for geometry to spontaneously generate designs based on text prompts, directly producing CAD geometry usable in product development and manufacturing processes.
Autodesk’s commitment to AI in design is long-standing, with its AI Lab established in 2018. The company’s approach to Neural CAD distinguishes itself by directly reasoning about CAD objects and industrial and architectural systems, moving beyond simply pairing large language models with existing solutions. These models are trained to reason at both detailed geometry and systems/industrial process levels, exploring concepts like efficient machine tool paths or standard building floorplan layouts.
