Line Profile
September 2026
Learn how Profile of a Line can simplify contour dimensioning, reduce tolerance stack complexity, and clarify design intent without tightening tolerances.
Perpendicularity
August 2026
See how perpendicularity establishes accurate 90-degree relationships between features to ensure proper fit, alignment, and functionality.
Parallelism
July 2026
Understand how parallelism keeps features uniformly aligned to a datum, improving part performance, consistency, and manufacturability.
Flatness
June 2026
Learn what flatness controls, when parallelism or profile is more appropriate, and how function-driven tolerances can prevent unnecessary machining and inspection costs.
Angularity
May 2026
Explore how angularity defines feature oreintation at specified angles and helps ensure precise relationships between features.
Position
March 2026
Learn how true position controls feature location, improves assembly fit, and serves as one of the most powerful tools in GD&T.
