Intro to CAD Modeling
Model parts digitally
CAD modeling creates precise 3D parts by sketching profiles, extruding, and constraining dimensions.
- sketch
- extrude
- constraints
- assembly
- export
Sketch
Draw 2D profiles with lines, arcs, and dimensions on reference planes.
Build
Extrude, revolve, or loft sketches into 3D features; apply fillets and chamfers.
Export
Assemble components and export STP/ STL for fabrication or sharing.

Rapid Prototyping Workflows
Rapid prototyping works best when sketches, models, and rough builds shorten feedback loops instead of pretending to be finished work.
How it works
Air Traffic Control
Air traffic control coordinates aircraft movements to maintain safe separation.
Comparison
Hydrogen Car vs EV
Hydrogen cars make electricity from fuel onboard, while EVs store electricity directly in batteries.
Examples
Lever Simple Machine
A lever multiplies force by pivoting around a fulcrum, trading distance for mechanical advantage.
