For aerospace students heading into industry
Aero Student Hub
Short, plain-language lessons for aerospace undergrad and master's students getting ready for internships and a first job. Each lesson works through one fictional example part, then gives you practice questions with the reasoning behind every answer.
Start at Industry, then GD&T. Or open the calculators.

Calculators
An isentropic flow calculator that runs in your browser, with a chart of the ratios against Mach number. A converging-diverging nozzle tool is coming later.
Lessons
From the Industry tab, GD&T topic (geometric dimensioning and tolerancing):
- Lesson 1 of 4 ~13 min read
Reading engineering drawings
You'll be able to find the part number, revision, material, units and default tolerances in a title block in under a minute.
Started
- Lesson 2 of 4 ~13 min read
Datums and the datum reference frame
You'll be able to tell a datum feature, its datum feature simulator and the datum apart on a real part and its inspection setup.
Started
- Lesson 3 of 4 ~13 min read
The feature control frame
You'll be able to name every compartment of a feature control frame and say what each one tells you, reading left to right.

- Lesson 4 of 4 ~13 min read
Form and orientation controls
You'll be able to describe the tolerance zone for flatness, straightness, circularity, cylindricity, perpendicularity, parallelism and angularity.
