The line along which two surfaces of a solid meet.

A line which represents distance.

Oblique pictorial where height, width, and depth are represented at full scale.

Line which shows where part is broken to reveal detail behind the part or to shorten a long continuous part.

Having the dimensions of height and width, height and depth, or width and depth only.

A measurable extent, such as the three principal dimensions of an object: width, height, and depth.

A rough representation of the main features of an object or scene and often made as a preliminary study.

A form of pictorial sketch in which all three drawing axes form equal angles of 120 degrees with the plane of projection.

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.

A drawing which contains views of an object projected onto two or more orthographic planes.

A series of thin lines used in a section view to indicate where the cutting plane line has cut through material. Similar to hatching in art.

Standardization of lines used on technical drawings by line weight and style.

Line which indicates dimensions of arcs, circles and detail.

A flat surface on which a straight line joining any two points would wholly lie.

A drawing that is used to show the material, size, and shape of a product for manufacturing purposes.

A sketch that shows an object's height, width, and depth in a single view.

A line which indicates that a very long objects with uniform detail is drawn foreshortened.

A heavy solid line used on a drawing to represent the outline of an object.

A dashed line type that shows interior detail not visible from the outside of the part.

Oblique pictorial where depth is represented as half scale compared to the height and width scale.

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.

A form of pictorial sketch in which vanishing points are used to provide the depth and distortion that is seen with the human eye.

Having the dimensions of height, width, and depth.

A three-dimensional body or geometric figure.

An outline of an object when viewed from one side.

1. A proportion between two sets of dimensions used to develop accurate, larger or smaller prototypes, or models. 2. A straight-edged strip of rigid material marked at regular intervals that is used to measure distances. Also referred to as a ruler.

A method of representing three-dimensional objects on a plane having only length and width.

Line which represents where a dimension starts and stops. Perpendicular to the dimension line.

A point in space, usually located on the horizon, where parallel edges of an object appear to converge.

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.

Lightly drawn lines used to layout a drawing and guide drawing of other lines such as object lines.

A line which defines the center of arcs, circles, or symmetrical parts.

An oval shape generated by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant and equal to the major axis
