Question | Answer |
---|---|
Construction Line | Thin lines that serve as guides while sketching or drawing. |
Depth | The distance from front to back. |
Documentation | 1. The documents that are required for something, or that give evidence or proof of something. 2. Drawings or printed information that contains instructions for assembling, installing, operating, and servicing. |
Edge | 1. The outside limit of an object, a surface, or an area. 2. The line along which two surfaces of a solid meet. |
Ellipse | 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. |
Freehand | Done manually without the aid of instruments such as rulers. |
Grid | A network of lines that cross each other to form a series of squares or rectangles. |
Height | The measurement of someone or something from head to foot or from base to top. |
Hidden Line | A line type that represents an edge that is not directly visible, because it is behind or beneath another surface. |
Isometric Sketch | A form of pictorial sketch in which all three drawing axes form equal angles of 120 degrees with the plane of projection. |
Line | 1. A long thin mark on a surface. 2. A continuous extent of length, straight or curved, without breadth or thickness; the trace of a moving point. 3. Long, narrow mark or band. |
Line Conventions | Standardization of lines used on technical drawings by line weight and style. |
Line Weight | Also called line width. The thickness of a line, characterized as thick or thin |
Manufacture | To make something, especially on a large scale using machinery. |
Measurement | The process of using dimensions, quantity, or capacity by comparison with a standard in order to mark off, apportion, layout, or establish dimensions. |
Multiview Drawings | Views of an object projected onto two or more orthographic planes. |
Object Line | A heavy solid line used on a drawing to represent the outline of an object. |
Oblique Sketch | A type of sketch involving a combination of a flat, orthographic front with depth lines receding at a selected angle, usually 45 degrees. |
Orthographic Projection | A method of representing three-dimensional objects on a plane having only length and breadth. Also referred to as Right Angle Projection. |
Perspective Sketch | A form of pictorial sketch in which vanishing points are used to provide the depth and distortion that is seen with the human eye. Perspective drawings can be drawn using one, two, and three vanishing points. |
Pictorial Sketch | A sketch that shows an object’s height, width, and depth in a single view. |
Plane | A flat surface on which a straight line joining any two points would wholly lie. |
Point | A location in space. Points have no dimensions. |
Profile | An outline of something as seen from one side. |
Projection Line | A horizontal or vertical line that can be used to locate entities in an adjacent view. |
Projection Plane | An imaginary surface on which the view of the object is projected and drawn. This surface is imagined to exist between the object and the observer. |
Proportion | 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. |
Scale | 1. A straight-edged strip of rigid material marked at regular intervals and used to measure distances. 2. A proportion between two sets of dimensions used in developing accurate, larger or smaller prototypes, or models of design ideas. |
Shading | The representation of light and shade on a drawing or map. |
Shape | The two-dimensional contour that characterizes an object or area, in contrast to three-dimensional form. |
Size | How large or small a person or thing is. |
Sketch | A rough drawing representing the main features of an object or scene and often made as a preliminary study. |
Solid | A three-dimensional body or geometric figure. |
Technical Working Drawing | A drawing that is used to show the material, size, and shape of a product for manufacturing purposes. |
Tone | The general effect of color or of light and shade in a picture. |
Vanishing Point | A vanishing point is a point in space, usually located on the horizon, where parallel edges of an object appear to converge. |
Views | Multiview projection. The six mutually perpendicular directions any object may be viewed are top, front, right-side, rear, left-side, and bottom. |
Visualize | To form a mental image of; imagine. |
Width | The measurement or extent of something from side to side. |
