How Ntop works

A new way to evaluate the full design space.

nTop replaces manual geometry drawing with design logic you program once, evaluate across thousands of variants, and trust to hold under any parameter change.

Capabilities

Built for design at scale.

Implicit Modeling
Scalable Design Exploration
Accelerated Physics
Knowledge Capture & Reuse
Geometry that never breaks

Parametric models stay stable no matter how far you push the parameters, so geometry never blocks iteration.

Thousands of variants in the time it took to build one

Encode design logic once, then run it across thousands of variants automatically, from desktop to distributed cloud compute.

Simulation feedback in minutes, not hours

GPU compute and machine learning cut simulation cycle times from hours to minutes, surfacing physics feedback early in the design process.

Engineering expertise that scales

Expert design logic encoded once in nTop persists across programs, cutting engineering investment on every one that follows.

Decisions backed by evidence
  • From evaluating a few concepts to exploring 1000’s of configurations.

  • From spreadsheet estimates and gut calls to decisions backed by physics.

  • From starting over each program to design logic that compounds across every one that follows.

Trusted by the Best

I’ve been in concept design for hypersonic vehicles for 25 years. I have never seen something as useful as nTop for advanced aircraft conceptual design.

Plug into your current process

nTop connects to existing CAD, simulation, and PLM tools and exports clean, watertight geometry downstream with minimal handoff friction. Machine-readable output feeds Physics AI and automated pipelines.

Frequently Asked Questions
  • Traditional CAD represents geometry as boundary representations (B-Rep) — collections of surfaces, edges, and vertices that can break when a design changes too much. Implicit modeling represents geometry as a mathematical function instead, so operations like fillets, booleans, and large parametric changes stay stable no matter how far you push them. That's what makes it possible to generate and evaluate thousands of design variants without manual repair between each one.

  • No. nTop is designed to work alongside your existing toolchain, not replace it. Most teams use nTop for early-stage design generation and exploration, then export to the CAD, CAE, and PLM tools they already trust for detailed design, final validation, and documentation. nTop exports to standard formats including STEP, Parasolid, STL, and 3MF, so your downstream workflow doesn't change.

  • nTop exports to standard CAD formats, including STEP, Parasolid, STL, and 3MF, plus direct mesh export for analysis tools and Convergent Body for modern CAD systems. On import, nTop reads standard CAD and mesh formats so you can bring in existing geometry as a starting point. If you have a specific format or tool you need to validate, our team can confirm compatibility before you commit.

  • nTop isn't an AI design tool itself — it's built to be the geometry infrastructure that AI tools run on. Because nTop notebooks encode design intent as structured, machine-readable workflows, they're compatible with Physics AI pipelines, surrogate model training, and AI agents, including ones you already use. nTop doesn't prescribe an AI strategy or lock you into one; it's built to plug into whatever AI environment your team is building with.

  • Engineers with CAD experience typically pick up nTop's core workflow quickly, since the underlying engineering concepts (parameters, constraints, design intent) are familiar — what's different is expressing them as a workflow instead of a sketch. nTop's Learning & Certification program is built to support that transition, from self-paced fundamentals through applications-engineer-supported pilot projects on real use cases.
