About GD&T pro
Learn, interpret and inspect GD&T according to ISO 1101. This app describes a large range of definitions of geometric dimensioning and tolerancing and supports engineers and employees as a multimedia reference book. As part of operative education, this app shows relationships and makes it easier to understand the right handling of form and position tolerances in practice.
This app explains the most important definitions of GD&T and its interpretation by examples (straightness, roundness, flatness, cylindricity, profile of a line, parallelism, squareness, angularity, position, concentricity, symmetry, circular runout, …)
