Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof. GD&T is used to define the nominal (theoretically perfect ...
A material condition in GD&T. Means that a feature of size is at the limit of its size tolerance in the direction that leaves the least material on the part. Thus an internal feature of size (e.g., a hole) at its biggest diameter, or an external feature of size (e.g., a flange) at its smallest thickness. The GD&T symbol for LMC is a circled L.
The types of information included are geometric dimensioning and tolerancing (GD&T), component level materials, assembly level bills of materials, engineering configurations, design intent, etc. By contrast, other methodologies have historically required accompanying use of 2D engineering drawings to provide such details.

ASME Y14.5 is a complete definition of geometric dimensioning and tolerancing. It contains 15 sections which cover symbols and datums as well as tolerances of form, orientation, position, profile and runout. [3] It is complemented by ASME Y14.5.1 - Mathematical Definition of Dimensioning and Tolerancing Principles.
The Praxis I, or Pre-Professional Skills Test (PPST), consisted of three exams: reading, writing, and mathematics. On September 1, 2014, ETS transitioned to the Praxis "CASE" or "Core Academic Skills for Educators" which also consists of reading, writing, and mathematics exams. These sections can be taken as a combined test or separately.
[1] Geometric dimensioning and tolerancing has provided geometrically defined, quantitative ways of defining flatness operationally. Flatness deviation may be defined in terms of least squares fit to a plane ("statistical flatness") or worst-case (the distance between the two closest parallel planes within). It can be specified for a given area ...
First-year composition (sometimes known as first-year writing, freshman composition or freshman writing) is an introductory core curriculum writing course in US colleges and universities. This course focuses on improving students' abilities to write in a university setting and introduces students to writing practices in the disciplines and ...
The Knowledge, Skills, and Abilities (KSA) framework, is a series of narrative statements that, along with résumés, determines who the best applicants are when several candidates qualify for a job. The knowledge, skills, and abilities (KSAs) necessary for the successful performance of a position are contained on each job vacancy announcement ...
