A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to a problem or to satisfy human needs and wants and winnow (narrow) down the possible solutions to one final choice.

The process of understanding a problem, devising a plan, carrying out the plan, and evaluating the plan in order to solve a problem or meet a need or want.

Systematic, scientific, documented study.

The distance from front to back.

Thin lines capped with arrowheads, which may be broken along their length to provide space for the dimension numerals.

A thin solid line perpendicular to a dimension line, indicating which feature is associated with the dimension.

A line type that represents an edge that is not directly visible because it is behind or beneath another surface.

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

Lines that are thin and used to connect a specific note to a feature.

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

A method of realistic drawing in which the part of an object closest to the viewer is a planar face, and all the lines describing sides perpendicular to that face can be extended back to converge at one point, the vanishing point

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

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

A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original. A model is often used to test ideas, make changes to a design, and to learn more about what would happen to a similar, real object.

Human activities used to create, invent, design, transform, produce, control, maintain, and use products or systems; a sequence of actions that combines resources to produce an output.

A detailed description of the design and materials used to make something.

The decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass.

A standard quantity in terms of which other quantities may be expressed.

A line type that is used to indicate the axis of symmetry for a part or feature.

The measurement of someone or something from head to foot or from base to top.

A straight line from the center to the circumference of a circle or sphere.

Having the dimensions of height, width, and depth.

A realistic way of drawing objects in three dimensions using a horizon line, a key edge, and two vanishing points.

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

The measurement or extent of something from side to side.

The use of a computer to assist in the process of designing a part, circuit, building, etc.

Occupying the same area in space.

Lying in the same straight line.

Circles or arcs that share the same center.

A limit to a design process. Constraints may be such things as appearance, funding, space, materials, and human capabilities. A limitation or restriction.

A cylindrical recess around a hole, usually to receive a bolt head or nut.

A conical-shaped recess around a hole that is often used to receive a tapered screw.

A change or correction made as a result of editing.

Make larger in area.

A distinctive attribute or aspect.

A rounded interior blend between two surfaces. Some uses are to strengthen joining surfaces or to allow a part to be removed from a mold.

Restrictions applied to geometric entities; for example, horizontal, parallel, perpendicular, and tangent.

A closed geometric figure in a plane formed by connecting line segements endpoint to endpoint with each segment intersecting exactly two others.

A straight line or plane that touches a curve or curved surface at one point.

Egyptian build pyramid. Measurement from elbow-middle finger.

Sailors measure depth of water. Measure from fingertip to fingertip.

Measure height of horses. Measure from tip of pinky to thumb.

Roman army used it to judge speed. From one step to another = 2 steps

Measurement around the stomach (Belt Measurement). Used in measuring fishing lines.

Width found by placing your 4 finger together.

An improvement of an existing technological product, system, or method of doing something.

A new product, system, or process that has never existed before, created by study and experimentation.

A method of shared problem solving in which all members of a group spontaneously, and in an unrestrained discussion, generate ideas.

A limit to the design process. Constraints may be such things as appearance, funding, space, materials, and human capabilities.

The factors (e.g., line, color, light, shadow, space, texture) that define a product and take into account the aesthetics and function of the product.

To observe or study by close examination and systematic inquiry.

A full-scale working model used to test a design concept by making actual observations and necessary adjustments.

Collecting data in a quantifiable manner.

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

Attach or position securely.

Designed to be practical and useful.

Parallel to the X axis.

Lines, planes, or surfaces side by side and having the same distance continuously between them.

At an angle of 90˚ to a given line, plane, or surface.

A triangle that has a 90 degree angle.

Parallel to the Y axis.

An act, process, or methodology used to make a design or system as effective or functional as possible within the given criteria and constraints.

A group of interacting, interrelated, or interdependent elements or parts that function together as a whole to accomplish a goal

The science and technology of building devices, such as electronic circuits, from single atoms and molecules.

The condition or quality of being true, correct, or exact; precision; exactness. The degree of correctness of a quantity or expression.

A measuring tool with two usually adjustable jaws used especially to measure thickness or diameter.

The degree to which several measurements or calculations show the same or similar results.
