Sketching & Dimensioning; 1. Flashcards
A line type that is used to indicate the axis of symmetry for part or feature.
Centerline.
Thin lines that serve as guides while sketching or drawing.
Construction Line.
The distant from front to back.
Depth.
A straight line passing from side to side through the center of a circle or sphere.
Diameter.
A measure able extent, such as the three principle dimensions of an object of width, height, and depth.
Dimension.
Thin lines capped with arrowheads. That may be broken a long their length to provide space for the dimension numerals.
Dimension Line.
A thin solid line perpendicular to a dimension line, indicating which feature is associated with the dimension.
Extension Line.
The measurement of someone or something from head to foot or from base to top.
Height.
A line type that represents an edge that is not directly visible because it is behind or beneath another surface.
Hidden Line.
A form of pictorial drawing in which all three drawing axes from equal angles of 120 degrees wth the plane of projection.
Isometric.
Lines that are thin and used to connect a specific note to a feature.
Leader Line.
Standardization of lines used on technical drawings by line weight and style.
Line Conventions.
Also called line width. The thickness of a line, characterized as thick or thin.
Line Weight.
Explanatory notes added to a drawing.
Annotation.
Dimensions that show the exact location of parts of an object.
Location Dimension.
A heavy solid line used on a drawing to represent the outline of an object.
Object Line.
A method of realistic drawing in which the part of an object closest to the viewers 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.
One-Point Perspective.
A method of representing three-dimensional objects on a plane having only length and breadth.
Orthographic projection.
A form of pictorial drawing in which the vanishing points are used to provide the depth and distortion that is seen with the human eye.
Perspective drawing.
A flat surface on which a straight line joining any two points would wholly lie.
Plane.
It’s straight line from the center to the circumference of a circle or a sphere.
Radius.
A proportion between two sets of dimensions use in developing accurate, larger, or smaller prototypes, or models of design ideas.
Scale.
Placed directly on a feature to identify a specific size or maybe connected to a feature in the form of the note.
Size dimension.
A rough drawing representing the main features of an object or seen and often made as a preliminary study.
Sketch.
Having the dimensions of height width and depth.
3D=three-dimensional.
It prime and preliminary a possible idea for a design. Most thumbnail sketches are not full-size and have little detail. They are intended to quickly explore possible alternative designs.
Thumbnail sketch.
Having the dimensions of height and width, height and depth, or width and depth only.
Two-dimensional.
A realistic way of drawing objects in three dimensions using horizon line, a key edge, two vanishing points.
Two-point perspective.
A point in space, usually located on the horizon, where parallel edges of an object appear to converge.
Vanishing point.
Views in shorthand for multiview projection, what is a system used to view an object. The six manually perpendicular directions any object may be viewed are top, front, right-side, rear, left-size, and bottom.
Views.
TI imagine the visual form of an object or situation that one cannot see.
Visualize.
The measurement or extent of something from side to side.
Width.
