Datum Point

A datum is a specific point or line on a structure that serves as a reference for measurements or other design purposes. It is used to establish a fixed starting point or level and is integral to all ideas that shape and fuel the world of Engineering. In architecture, a datum can be defined as a horizontal or vertical reference plane, line, or

Datum Feature The actual, physical part of a component used to establish a datumsuch as the surface of a flange, the center of a hole, or the axis of a pin. Datum The theoretical plane, point, or axis derived from a datum feature. For example, the center of a hole is the datum feature the axis running through the center is the datum.

Learn what a datum target is and how to use it in geometric dimensioning and tolerancing GDampT. See different types of datum targets, such as points, lines, and areas, and how to identify them on a drawing.

Datums are fixed reference points, lines or planes used to locate and measure features on a part. Learn about the types, notation and applications of datums in engineering, such as quality control, automotive, aerospace and civil engineering.

Learn what a datum is, how it is used, and how to dimension it in GDampT. A datum is a reference point for measurements and a theoretically perfect feature that can be a plane, point, or axis.

Learn what datums are in geometric dimensioning and tolerancing GDampT, how to use them to measure and inspect parts, and how to classify them according to different symbols. Find out the difference between datum and datum feature, datum reference frame, datum target, and more.

Learn what a datum feature is, how to identify it on a drawing, and how to use it in geometric dimensioning and tolerancing. A datum feature is a tangible surface or feature of size that is used as a reference for other features on a part.

Learn the definition, types, and drawing indications of datums, which are references for processing and measuring dimensions of a target. Datums can be established by datum features, simulated datum features, or datum systems.

In manufacturing, a datum is an exact reference point, line, axis, or plane used to measure and ensure precision. These reference points are crucial for defining the geometry of objects and establishing tolerance zones, which ensure parts fit together correctly and function as intended. Role of Datums in Manufacturing

A datum reference is a geometric feature that serves as a reference for measuring or defining an object. Learn about different types of datums in carpentry, aviation, engineering, and geodesy.
