|
|
| concurrent | (adj.) The technique of organizing numerous steps so that they happen in parallel rather than one after another (serially). Concurrent engineering, for example, involves all members of the design process working simultaneously in close coordination with each other rather than each member waiting for other members to finish with their components of the design.

|
|
|
| conventions | (n) Commonly accepted practices, rules, or methods. In technical drawing, a convention is the use of dashed lines to designate a feature hidden from the current viewpoint.
(See 11)
|
|
|
|
| design process | (n) The method used to create a solution to an engineering or technical problem. The result is often a product, either one of a kind or mass produced. The design process, though unique to each problem, typically includes standard stages and uses graphics to communicate information between and within these stages.

|
| drawing | (n) a graphical representation of objects and structures and is done using freehand, mechanical, or computer methods.
(See 4)

|
|
|
| engineer | (n) A professional concerned with applying scientific knowledge to practical problems. The discipline is divided into a number of specialties, such as civil, mechanical, chemical, electronic, aerospace, electrical, and industrial engineering.

| GKS (Graphical Kernal System) | (n) A software program that can generate, display, and transfer computer graphics data in a comparative format.
(See 12)

| HOOPS (Hierarchical Object-Oriented Picture System) | (n) A software program that can generate, display, and transfer computer graphics data in a compatible format.
(See 12)
|
|
|
|
| ideation | (n) A structured approach to thinking for the purpose of solving a problem, often employing graphics. Ideation is the conceptual phase of the design process. Feasibility studies are often performed to define the problem, identify important factors that limit the scope of the design, evaluate anticipated difficulties, and consider the consequences of the design.
(See 8)

|
|
| isometric grid | (n) A network of evenly spaced lines drawn at 30, 90, and 120 degrees. Paper preprinted with this grid is used to sketch isometric drawings.
(See 35)
|
|
|
|
| media | (n) A means of conveying information, both graphic and textual. Traditionally, this refers to the types of paper used in drafting; more recently, it has also come to refer to the types of information storage and playback technology, such as video, audio, CD-ROM, etc.
(See 16)
|
|
|
|
| modeling | (v and n) Often referred to as geometric modeling, which is both a process and a product. Modeling is used to analyze preliminary and final design solutions, as well as provide input to the production process in the form of a computer database. Modeling is a product since it is a result of the design process, which uses graphics as a tool to visualize possible solutions and to document the design for communications purposes.

|
| negative space sketching | (n) A technique where you concentrate on sketching the space between the objects and not on the object itself.
(See 40)

|
| revision block | (n) An area located next to the title block, listing the version, or revision, of the drawing depicted.
(See 55)
|
|
|
|
| SI | (n) Acronym for System Internationale (i.e., International System of Units), the metric measurement system. For technical drawings using the SI units, the millimeter (mm), meter (m), and the kilometer (km) are the most common units of measure. The international organization that established the metric standard is the International Standards Organization (ISO).
(See 22)
|
|
|
|
| standards | (n) Sets of rules that allow for the clear communication of technical ideas by governing how parts are made and represented in technical drawings. In the United States, the American National Standards Institute (ANSI) is the governing body that sets the standards used for engineering and technical drawings.
(See 12)
|
|
|
|
| technical drawing/graphics | (n) A specialized type of graphics used to communicate technical information. Examples of technical graphics include 3-D computer models and illustrations of a technical device.
(See 5)
|
|
|
|
| technologists | (n) Personnel who work with the engineers and are concerned with the practical aspect of engineering in planning and production. The technologist must be able to communicate quickly and accurately using graphics, by sketching design problems and solutions, analyzing design solutions, and specifying production procedures.

|
| text alignment | (n) The vertical alignment of lines of text. Also referred to as justification, lines of text can be aligned along such features as their right or left ends or the centers of the lines.

| tools | (n) Devices used to create engineering drawings and models, including both hand and computer tools.
(See 14)
|
|
|
|
| traditional tools | (n) Devices used to assist the human hand in making technical drawings, such as drawing lines straighter, circles more circular, etc. Examples are mechanical pencils, straightedge scales, triangles, and compasses. Traditional tools are often compared with computer-based CAD tools.

|
| upside-down sketching | (n) A technique for improving sketching ability by turning an object upside-down before sketching.

|
| visualization | (v) The process of mentally understanding visual information. Visualization is used with both physical and virtual models to better understand their form and function. The mental image may be analogous to the object represented or of something different. Graphics and the process of creating graphics are used to help stimulate the visualization of proposed designs.
