nTop
Computational design for high-performance engineering
About
nTop is computational design software that lets engineers build reusable models of entire design spaces — topology optimization, lattices, variable shelling, conformal ribbing — on an unbreakable implicit modeling kernel instead of manual CAD drafting. Computers then explore the design space against custom objectives, which suits aerospace, defense, automotive, and medical teams; the company says 400+ companies use it, and it acquired CFD vendor cloudfluid in 2026. It integrates with Autodesk Fusion, Materialise Magics, and EOS printers, but it is an enterprise-grade engineering tool, not a casual 3D modeler.
What it can do
- Implicit modeling kernel
- Topology optimization and lattices
- Design process automation (nTop Automate)
- Developer library (nTop Core)
- CAD/CAE/AM integrations
