Creating a Parametric Jet Model with nTop Blocks

In this demo, you’ll see how a complete parametric jet model was built in nTop using custom reusable blocks.

Everything in the model is driven by fields and relationships: wing geometry, duct positioning, tail thickness, and even blend transitions update instantly as parameters change. Unlike traditional CAD, nothing breaks, even under major configuration shifts.

What makes this powerful is how each component was packaged into modular, user-defined blocks. The fuselage, wings, ducts, and vertical tails are all constructed with implicit modeling, then turned into shareable blocks for rapid reuse. It’s a hands-on look at how engineering teams can create flexible design systems that evolve with their concepts.

It’s a real-world look at what’s possible when engineering speed meets intelligent automation.
