The total amount of variation in a part's position when rotated around a datum axis.

Dimensions that show the exact theoretical location of features on a part.

Methods for conveying measurements on technical drawings.

Rules for writing millimeter dimensions on drawings.

Rules for writing inch dimensions on drawings.

Dimensioning method where features are measured relative to each other.

Spacing requirements for dimension lines on drawings.

Lines extending from object geometry, used for specifying dimensions.

Information that applies to the entire drawing and is generally written at the lower right-hand corner.

The condition where all dimensions and tolerances apply to a part that is not constrained (or held).

Indicates that a feature is repeated exactly in the drawing a certain number of times.

All deviation is in one direction from the basic size.

Tolerance where the deviation is displayed with the high limit above the low limit.

Places a single dimension between two key points, minimizing tolerance accumulation.

Assigns tolerances based on statistical practices, not conventional methods.

Ensures a clearance or space exists between mating parts.

Ensures an interference of material always exists between mating parts.

Allows either a clearance or interference fit depending on the assembly.

Measuring parts after machining and matching them to appropriate mating parts.

The difference between the maximum material limits of mating parts.

A dimensioning method where all dimensions in a given direction start from a common base or datum.

The acceptable variation in a dimension.

Fits for parts where location accuracy is important, but small clearances/interferences are allowed.

Tolerances for individual shape characteristics (like straightness, flatness, circularity and cylindricity).

A 2D tolerance zone defined by two contours; controls the shape and size of the contour.

Controls the location and orientation of a feature (center, axis, plane) relative to datums.

Baseline dimensioning uses a common origin while chain dimensioning measures from feature to feature.

The part of a drawing where geometric tolerance information is written.

Circles are dimensioned by diameter, arcs by radius.

Chamfers are dimensioned by length and angle, or two distances.

A datum plane established using a single point contact with a specified surface, perpendicular to the primary and secondary datum surfaces.

The state where a feature of size contains the maximum possible amount of material within its specified size limits.

A 3D tolerance zone controlling the orientation of a surface or axis relative to a datum.

The shape of an angular tolerance zone creates a wedge, where more tolerance is allowed at one end than the other.

A geometric tolerance that controls the axis-to-axis relationship between two features.

A 2D tolerance that controls how a surface varies relative to a datum axis as it rotates.

Applying tolerances too tightly makes manufacturing more difficult and costly.

Applying tolerances too loosely can lead to parts malfunctioning.

Conventional tolerancing can only control the size of a feature.

A tolerance that controls the total amount of variation in a part's position when rotated around a datum axis. It ensures that the part stays within specified limits as it rotates.

A method of tolerancing where the maximum and minimum acceptable dimensions are specified as deviations from a basic size.
