Term
Drawing
Definition
A formal graphical representation of an object containing information based on the drawing type.
Term
Edge
Definition
The line along which two surfaces of a solid meet.
Term
Ellipse
Definition
A regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points is constant, or resulting when a cone is cut by an oblique plane which does not intersect the base.
Term

A form of pictorial sketch in which all three drawing axes form equal angles of 120 degrees with the plane of projection.
Term
Leader Line
Definition
Line which indicates dimensions of arcs, circles and detail.
Term
Line
Definition

Term
Line Conventions
Definition
Standardization of lines used on technical drawings by line weight and style.
Term
Line Weight
Definition
Also called line width. The thickness of a line, characterized as thick or thin.
Term
Long-Break Line

A line which indicates that a very long objects with uniform detail is drawn foreshortened.
Term
Manufacture
Definition
To make something, especially on a large scale using machinery.
Term
Measurement
Definition
The process of using dimensions, quantity, or capacity by comparison with a standard in order to mark off, apportion, lay out, or establish dimensions.
Term
Multi-View Drawing
Definition
A drawing which contains views of an object projected onto two or more orthographic planes.
Term
Object Line
Definition
A heavy solid line used on a drawing to represent the outline of an object.
Term
Oblique Sketch
Definition
A form of pictorial in which an object is represented as true width and height, but the depth can be any size and drawn at any angle.
Term
Orthographic Projection
Definition
A method of representing three-dimensional objects on a plane having only length and breadth. Also referred to as Right Angle Projection.
Term
Perspective Sketch
Definition
A form of pictorial sketch in which vanishing points are used to provide the depth and distortion that is seen with the human eye.
Term

Definition
A sketch that shows an object’s height, width, and depth in a single view
Term
Plane
Definition
A flat surface on which a straight line joining any two points would wholly lie.
Term
Point
Definition
A location in space.
Term
Profile
Definition

Term
Projection Line
Definition
An imaginary line that is used to locate or project the corners, edges, and features of a three-dimensional object onto an imaginary two-dimensional surface.
Term
Projection Plane
Definition
An imaginary surface between the object and the observer on which the view of the object is projected and drawn.
Term

Definition
1. The relationship of one thing to another in size, amount, etc. 2. Size or weight relationships among structures or among elements in a single structure.
Term
Scale
Definition
1. A straight-edged strip of rigid material marked at regular intervals that is used to measure distances. 2. A proportion between two sets of dimensions used to develop accurate, larger or smaller prototypes, or models.
Term
Section Lines
