Projection Planes
Imaginary 2D plane, like a sheet of clear glass, placed parallel to a principal face of the object to be visualized.
Regular Views
In a multi view drawing, this term refers to an object's front, top, bottom,right, left, and back views.
Miter Line
In drawings created with orthographic projection techniques, an construction line drawn at 45 degrees that enables info to be projected from the top view to side view and etc.
Linetype
Include visible lines, which show the visible edges and features of an object; hidden lines which represent features that would not be visible; and center lines, which locate the centers of features such as holes and arcs.
Sheet Sizes
Technical drawings are created on standardized sheet sizes.
Orthographic Projection
Technique employed in the creation of multi view drawings to project geometric info.
Third-Angle Projection
Technique for arranging multi view drawings with the top view above the front view and the right side drawn tho the right of the front view.
CAD Designers
Term often used to describe the creation of technical drawings.
Engineering Graphics Mechanical Drafters
Term often used to describe the creation of technical drawings.
Foreshortening
Term used to describe the phenomenon that occurs when a feature on an inclined plane is not shown true size or true shape in a multi view drawing.
National Society of Professional Engineers
The accrediting agency for engineers.
American Institute of Architects
The accrediting body for architects.
How does a drafter determine which view will be the front view?
Which ever side has the most features.
Inclined Plane
A plane located on an object in a multi view drawing that is sloping and is not perpendicular to the line of sight of the viewer.
First-Angle Projection
A technique for arranging multi view drawings in which the left side view is drawn to the right of the front view and the top view is placed below the front view and so on.
