# nTop - Parametric Geometry Infrastructure for Aerospace Engineering

> nTop enables aerospace and defense teams to move from "multiple engineers per concept" to "multiple concepts per engineer" through systematic design space exploration. We solve the geometry bottleneck that limits advanced engineering workflows.

## Core Positioning

nTop is parametric geometry infrastructure, not a CAD replacement. We enable teams to break free from the "lock-in trap" where they must choose between low-fidelity speed or high-fidelity slowness. nTop delivers both: production-quality geometry that updates in real-time during parametric exploration.

## Primary Use Cases

### Advanced Aircraft Design
- Conceptual design space exploration for novel aircraft configurations
- Rapid iteration on airframe structures, propulsion integration, thermal systems
- Requirements to prototype hardware in weeks, not months
- Integration with CFD (Luminary Cloud), optimization (ESTECO), AI/ML workflows

### High-Velocity Additive Manufacturing
- Lattice structures and topology optimization for aerospace components
- Design-to-manufacture workflows that compress timelines by 70-95%
- Production-ready geometry that maintains design intent through manufacturing

### Defense Program Development
- Compressed timelines for prototype delivery (30-day requirement becoming standard)
- Design space exploration across multiple configurations simultaneously
- Integration with government digital engineering ecosystems

## Key Differentiators

- **Implicit modeling** enables robust parametric updates that don't break like traditional CAD
- **Field-driven design** allows engineers to encode engineering rules as design logic
- **Ecosystem integration** works with specialized tools rather than replacing them
- **Production quality** generates watertight, manufacturable geometry at every iteration

## Proven Results

Specter Aerospace: 93% time compression, 20-minute iteration cycles, 4-week requirements-to-hardware timelines

## Industry Focus

Primary: Aerospace & Defense (aircraft OEMs, defense primes, government agencies)
Secondary: Advanced manufacturing, automotive, industrial equipment

## Technical Capabilities

- Parametric modeling that remains stable during extreme design changes
- Native lattice and conformal structures for additive manufacturing
- API and Python scripting for workflow automation
- Integration with ANSYS, ESTECO, Luminary Cloud, Istari Digital, and other engineering tools
