  1. Engineering Draft 1 Final Test Please look over all the information in the whole test. Once you have completed this, ask any questions pertaining to the information that is unclear to you. If you understand what to do, then proceed with the test. There are four main areas in this test, Multiple Choice (30 pts), Section Identification (9 pts) and Line Identification (14 pts). Please work silently and alone.

  2. Multiple Choice (2 ea/30 points) 1. If a unidirectional system is used to dimension, all dimensions must read from the _______. • From the edge of the project. • From the bottom of the sheet. • From the right of the sheet. • Parallel with the edge of the project. 2. According to your workbook, when should dimensions be duplicated? • If it is convenient • When it adds clarity • Never • None of the above 3. The radius of an arc should always be given with the abbreviation of _____. • RAD • R • r • RDS

  3. 4. The most common symbol for diameter is given by ______. • DIAM • E • D • A & B 5. According to your workbook, the two most popular ways to properly dimension angled surfaces ______ and ______. • Polar and Angular • Angular and location • Coordinate and location • Coordinate and angular. 6. In a section view we can tell what the material is by… • The way the material looks • The design of the hatch lines • Knowing what the draftsmen’s intentions are. • Understanding what would be best used. 7. In isometric views, what three angles are primarily used to layout a drawing? • 30, 30, and 90 degrees • 30, 150, and 90 degrees • 15, 30 and 45 degrees • 15, 30 and 90 degrees ms.yccd.edu

  4. 8. Section Views are used when… • The item that is being drawn is in pieces • The item is to big to draw on the paper • When there is unseen information that needs to be revealed • When we want to show how pieces are fit together with other pieces. • 9. When referring to picture-like drawings, we are generally referring to ______. • Cabinet Drawings • Isometric Drawings • Orthographic Drawings • The Cover Page • 10. When dimensioning a circle, it is good practice to locate its position within the object by identifying the distance from the edge of the object to the: • Quadrants • Outer edge of the circle • Center Point • Radius • 11. Since it is not good practice to dimension to hidden lines, we have the option to: • Find another location to place the dimension where the lines are not hidden. • Use section views to expose the hidden information, and then dimension. • Leave it without dimensions. • A or B • 12. When using good dimensioning technique, a space of no less than _______ inch should be left between the object and the first dimension line. • 1/2 • 3/8 • 1/4 • 3/5

  5. 13. A circle that is viewed at an angle other than 0 or 90 degrees is called_______. • Acute circle. • Cylinder • Oval • Ellipse • 14. Identify the following line ______ _ ______ _ _______. • A Phantom line. • A Centerline. • A Hidden line • My pen is running out of ink. • When dimensioning an object that end with an arc or rounded surface, the drafter should dimension to the _____ and give the _______. • End/radius • End/diameter • Center/radius • Center/overall Section Identifying(3ea/9 Points)
