From requirements to design in minutes, not months.
nTop's unbreakable parametric models let you explore hundreds of design variants systematically—with manufacturing constraints, performance requirements, and analysis built in.
Trusted by 450+ leading engineering teams
Engineering is being outpaced by its own ambition.
Product development timelines are shrinking. Performance demands are rising. Yet most teams still rely on brittle tools that force early design lock-in before tradeoffs are explored or risks understood. With nTop, you can generate, explore, and validate geometry automatically, insightfully, and without fragility to meet mission requirements.
Traditional CAD Process
model → test → rework
- CAD models that can’t adapt as requirements shift
- Simulation as a bottleneck, not a guide
- Architecture decisions made on assumptions
nTop Process
define → explore → validate
- Geometry that adapts as constraints evolve.
- Simulation in the loop, not as an afterthought.
- Logic you can trace, audit, and adapt.
Design faster. Decide smarter. Deliver with confidence.
Whether in early research, iterative development, or production optimization, nTop accelerates engineering workflows at every stage

Why nTop works where other tools break
nTop accelerates iteration and empowers high-confidence decisions across every design phase. Here’s how leading teams apply it:
Iterate while you design
Iterate without fragile geometry
Iterate without fragile geometry
Logic-driven modeling means no crashes, rebuilds, or rework. Make changes instantly, even to complex models, and explore 10x more options without debugging.
Simulate while you design
Simulate while you design
With embedded FEA and CFD in the loop, you get physics insight as you build, reducing trial and error and surfacing risks before they cost you.
Scale your design logic
Scale your design logic
Capture engineering intent once and reuse it across variants, missions, and programs. What used to be tribal knowledge becomes shareable, adaptable design code.
4-hour
Total modeling time versus 4 weeks using traditional tools
If you'd have to spend five hours to do it in CAD, but you could do it in 5 minutes in nTop, why wouldn't you?

Faster feedback loop from simulation to design
The real value with nTop is its ability to accelerate our dev cycles so we can test and validate ideas as quickly as possible.

Unique parts optimized using the same, reusable computational model
We can generate hundreds of lightweight design candidates in every sprint to meet our aggressive timelines and weight reduction targets.
