Engineering Design 1 - Week 16 Lecture - Detailing Engineering Drawing

Tolerance

The permissible limit of variation in a physical dimension of an object.

Multi-view Projection

A drawing method that displays multiple views of an object, aligned with the same axis.

Auxiliary View

A view that displays a plane parallel to an angled plane with true dimensions.

Section View

A drawing view that shows inner details of a component by cutting through it with a specified plane.

Detail View

An enlarged view of a specific area of a drawing, highlighting details typically not visible in standard views.

Broken-out Section View

A portion of an existing view where material is removed to expose inner details.

Break View

A drawing view that adds a break line to the view to indicate a section that has been removed.

Crop View

A drawing view that allows cropping of an existing view to focus on a specific area.

Centerline

A line that indicates the center position of revolved features in a drawing.

Center Mark

A mark used to indicate the center of circular features or revolved features.

Annotations

Notes and explanations added to a drawing to provide additional information.

Title Block

A section of a drawing that includes essential information such as title, scale, projection type, and author.

Dimensional Tolerance

The total permissible variation of a feature's size, which includes limits for both upper and lower sizes.

First Angle Projection

A method of projection where the object is placed between the observer and the plane.

Third Angle Projection

A method of projection where the plane is placed between the observer and the object.

Engineering Drawing

A detailed drawing that communicates how a part should be manufactured or assembled.

Dimensional Values

Specific measurements used in engineering drawings that define the size and extent of an object.

Gear Sub-assembly

A component that consists of interconnected parts designed to work together within a larger assembly.

Projection Type

The method used to create the visual representation of an object on a drawing, either first angle or third angle.
