ASME - Answer✔✔-American Society of Mechanical Engineers
Half Scale - Answer✔✔-1:2
orthographic projection - Answer✔✔-A two dimensional drawing of the front, top, and side views of an
object
Pictorial drawing - Answer✔✔-a drawing that shows an object as it appears to the human eye, includes
isometric and perspective drawings
Layers - Answer✔✔-used to make lines of varying colors and widths on CAD drawings
Isometric projection - Answer✔✔-three dimensional drawing made up of equal angles of 120 degrees,
most common 3-D drawing used in industry
Oblique projection - Answer✔✔-three dimensional drawing where the front faces forward, and the
depth dimensions go back at angles, usually 15, 30, or 45 degrees. Used when most information on
drawing is on the front of the object.
Perspective - Answer✔✔-three dimensional drawing that depth lines disappear to a vanishing point.
Used mainly in architectural presentations
Hidden line - Answer✔✔-For a three-dimensional object, a line that cannot be seen because view of it is
obstructed by part of the object or of another object.
