Unit Overview

What Unit 2 Builds

You will move from sketch-based documentation into controlled, editable, fabrication-ready CAD models.

CAD Control

Sketch constraints, dimensions, parameters, and features make models precise and editable.

Aerospace Parts

Nose cones, fins, mounting features, and printed testers connect CAD tools to aerospace design decisions.

Fabrication Evidence

Slicer previews, print settings, measurements, and fit tests connect digital models to physical parts.
