Fundamentals of Aerospace Vocab (Projects 1-3)

Front

2D Model

Back

A sketch or CAD drawing that displays surfaces or simple two-dimensional views (X and Y, for example) of an object. 2D models can be 'extruded' to create a 3D solid model using CAD software.

Front

3D Model

Back

A three-dimensional drawing that represents an object’s length, width, and depth. 3D drawings can be 'wireframes' or can be converted into 3D solid models.

Front

Assembly

Back

A group of machine or handmade parts that fit together to form a self-contained unit.

Front

Asymmetry

Back

Symmetry in which both halves of a composition are not identical. It can also be referred to as informal balance.

Front

Auxiliary View

Back

An orthographic view of an object using a direction of sight other than one of the six basic views (front, top, right side, rear, bottom, left side). Used to show a surface that is not parallel to any of the principal view planes.

Front

Axis

Back

An imaginary line through a body, about which it rotates; an imaginary line about which a regular figure is symmetrically arranged; a fixed reference line for the measurement of coordinates.

Front

Computer-Aided Design (CAD)

Back

For design, the use of a computer to assist in the process of designing a part, circuit, building, etc. For drafting, the use of a computer to assist in the process of creating, storing, retrieving, modifying, plotting, and communicating a technical drawing.

Front

Collinear

Back

Points lying on the same straight line.

Front

Concentric

Back

Concentric circles share the same center, axis, or origin, with one inside the other. Concentric circles do not necessarily have the same radius.

Front

Coplanar

Back

Two coplanar lines are said to be parallel if they never intersect.
