Certified Drafting Exam
1. ASME: American Society of Mechanical Engineers
2. Half Scale: 1:2
3. orthographic projection: A two dimensional drawing of the front, top, and side views of an object
4. Pictorial drawing: a drawing that shows an object as it appears to the human eye, includes isometric and perspective
drawings
5. Layers: used to make lines of varying colors and widths on CAD drawings
6. Isometric projection: three dimensional drawing made up of equal angles of 120 degrees, most common 3-D drawing used
in industry
7. Oblique projection: 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.
8. Perspective: three dimensional drawing that depth lines disappear to a vanishing point. Used mainly in architectural
presentations
9. Hidden line: 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.
10. General assembly: an orthographic drawing of multiple parts that shows relationship of parts to each other in a
mechanism
11. Bill of materials: A document that show the quantity of each type of direct material required to make a product
12. Simplified thread representation: simple method of drawing threads on an orthographic drawing
13 Detailed thread representation: exact drawing representation of a given thread type

14. UCS: user coordinate system - used in the construction of 3D solids in AutoCAD 15. Vanishing point: used in perspectives
for determining the direction of the depth lines
16. Elevation: used in architecture to show exterior views of buildings
17. Floor plan: horizontal section through building, shows width and depth of building
18. Building section: vertical cut through house, used to show construction components of building
19. Window and door schedule: used to define specific size requirements of openings in the building
20. 2 foot minimum: counter space requirements on either side of sink
21. 1 1/2" x 3 1/2": actual size of framing member
22. 2 x 6: nominal size of a framing member
23. Square footage cost: an estimated cost used by architects to begin schematic design process
24. Program: used by architect to design buildings to the client's wants and needs
25. Design Budget: amount of money that clients have to spend on cost of building
26. Exploded Assembly: pictorial drawing of mechanism to show how parts interrelated to each other
27. Hatching: used in AutoCAD to show various materials in sectional drawings
28. Diameter: The distance from one side of a circle to the other, running directly through the circle's center
29. Cylinder: A geometric figure with a uniform circular cross-section through its entire length.
30. Angle: The figure formed by two lines coming together.
31. Dimension Line: A line that normally runs between two extension lines, has arrows or ticks at its ends, and has a value at
its center.
32. Hexagon: A six-sided figure with each side forming a 60Ú angle.
33. Bisect: To divide into two parts of equal size or length.
34. Border: The heaviest line used in drafting, acts as a "frame" for the drawing.
35. Centerline: A fine line composed of long and short dashes with spaces in between used to indicate the center of a
symmetrical object.
36. Circumscribe: To draw around.
37. Concentric: Having a common center.
38. Coordinates: The positions or locations of points on the X, Y, and Z planes.
39. CPU: The part of the computer that processes input information.
40. Fillet: A curved surface connecting two surfaces which form an angle.
41 Grid: A CADD drawing aid formed by a network of uniformly spaced points or lines on the screen.
