Terms in this set (37)
draw a shape, line or angle accurately using a compass and straightedge
is a two-dimensional drawing of a three-dimensional object, using two or more additional drawings
is a technique of illustration by which a standardized series of orthographic two-dimensional pictures is constructed to represent the form of a three-dimensional object.
Section view drawing
drawing to show an area or hidden part of an object by cutting away or removing some of that object.
A view of an object (actual or imagined) as it would be seen by an observer who looks at the object either in a chosen direction or from a selected point of view
pictorial representation of an object in which all three dimensions are drawn at full scale rather than foreshortening them to the true projection
is a technique used to represent three-dimensional images on a two-dimensional picture plane
line by which a figure or object is defined or bounded
used to represent surfaces that are not directly visible in the orthographic view
real or imaginary line through the center of something, especially one following an axis of symmetry.
thin line, broken in the middle, with arrowheads at each end
line that establishes the drawing space of a plan
a line that establishes a connection between a graphical representation of an item and some text
cutting plane line
dashed lines, that extend past the edge of the object 1/4" or 6mm and have line segments at each end drawn at 90 degrees and terminated with arrows. Indicates the surface to be seen in a section drawing
used to indicate imaginary features such as alternate positions of moving parts and adjacent positions of related parts
Light lines used to draw initial lines that are later converted to object lines
an imaginary line about which a body rotates.
of or denoting circles, arcs, or other shapes that share the same center, the larger often completely surrounding the smaller.
a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.
is any of the line segments from its center to its perimeter, and in more modern usage, it is also the length of any of them
informal drawing used to convey ideas
A line which touches a circle or ellipse at just one point
Third angle projection
method of orthographic projection which is a technique in portraying a 3D design using a series of 2D views using right side, plan and front views.
t right angles to a horizontal plane; in a direction, or having an alignment, such that the top is directly above the bottom
drawing triangle with set angles
a template used for drawing curved lines
an instrument for measuring angles, typically in the form of a flat semicircle marked with degrees along the curved edge.
an instrument for drawing circles and arcs and measuring distances between points, consisting of two arms linked by a movable joint, one arm ending in a point and the other usually carrying a pencil or pen.
drawing tools with set units used to easily develped proportional drawings
the ratio of the linear dimensions of the object as represented in a drawing to the actual dimensions of the same.
process of forming letters, numerals, and other characters in technical drawing
is a rounding of an interior or exterior corner of a part design.
An interior or exterior corner, with an angle or type of bevel
is a line which has zero slope value
(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them.
a set of values that show an exact position.
