Innovation -ANSWER✅✅✅✅An improvement of an existing technological product,
system, or method of doing something.
Invention -ANSWER✅✅✅✅A new product, system, or process that has never existed
before, created by study and experimentation.
Design Brief -ANSWER✅✅✅✅A written plan that identifies a problem to be solved, its
criteria, and its constraints. The design brief is used to encourage thinking of all aspects
of a problem before attempting a solution.
Design Process -ANSWER✅✅✅✅A systematic problem-solving strategy, with criteria
and constraints, used to develop many possible solutions to solve a problem or satisfy
human needs and wants and to winnow (narrow) down the possible solutions to one
final choice.
Construction Line -ANSWER✅✅✅✅Thin lines that serve as guides while sketching or
drawing.
Hidden Line -ANSWER✅✅✅✅A line type that represents an edge that is not directly
visible, because it is behind or beneath another surface.
Isometric Sketch -ANSWER✅✅✅✅A form of pictorial sketch in which all three drawing
axes form equal angles of 120 degrees with the plane of projection.
Multiview Drawings -ANSWER✅✅✅✅Views of an object projected onto two or more
orthographic planes.
Object Line -ANSWER✅✅✅✅A heavy solid line used on a drawing to represent the
outline of an object.
Oblique Sketch -ANSWER✅✅✅✅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 -ANSWER✅✅✅✅A method of representing three-dimensional
objects on a plane having only length and breadth. Also referred to as Right Angle
Projection.
Perspective Sketch -ANSWER✅✅✅✅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.
Shading -ANSWER✅✅✅✅The representation of light and shade on a drawing or map.
Technical Working Drawing -ANSWER✅✅✅✅A drawing that is used to show the
material, size, and shape of a product for manufacturing purposes.
Tone -ANSWER✅✅✅✅The general effect of color or of light and shade in a picture.
ANSI -ANSWER✅✅✅✅American National Standards Institute: A private, non-profit
organization that coordinates the development and use of voluntary consensus
standards in the United States.
Dimension Lines -ANSWER✅✅✅✅Lines that are thin lines capped with arrowheads,
which may be broken along their length to provide space for the dimension numerals.
Extension Lines -ANSWER✅✅✅✅Thin lines used to establish the extent of a
dimension. Extension lines begin with a short space from the object and extend to about
.125 inches past the last dimension line. Extension lines may cross object lines, center
lines, hidden lines, and other extension lines, but may not cross dimension lines.
International Organization for Standardization (ISO) -ANSWER✅✅✅✅A non-
governmental global organization whose principal activity is the development of
technical standards through consensus.
Mean -ANSWER✅✅✅✅The average or central value of a set of quantities.
Median -ANSWER✅✅✅✅Referring to the middle term or mean of the middle two
terms of a series of values arranged in order of magnitude.
Mode -ANSWER✅✅✅✅The value that occurs most frequently in a given data set.
Numeric Constraint -ANSWER✅✅✅✅A number value, or algebraic equation that is
used to control the size or location of a geometric figure.
Annotate -ANSWER✅✅✅✅To add explanatory notes to.
