   Note: This question must be printed to be completed. Print this question.

1. Diameter
2. Radius
3. Square
4. Deep

8. True or False? It is permissible for extension lines to cross each other, but, if possible, dimension lines should not cross each other.
     A. True B. False
9. If the dimension line is an arc, this is an indication that the dimension is a(n) _____ dimension.
   
10. What term is applied to placing dimensions in the view where the shape is shown?
    
11. True or False? Cylinders are dimensioned by a leader line pointing to the circle view and a linear dimension that shows the length or height.
      A. True B. False
12. What is the term applied to aligning sub-dimensions arrowhead-to-arrowhead across the view?
    
13. All dimensions can be grouped into two categories: _____ and _____.
    
    
14. True or False? Reference dimensions should be indicated by placing the numeric value in parentheses.
      A. True B. False
15. If a dimension does not have a numeric value, but just an alphabetic character, where might the dimension value be found?
      A. In a table. B. In a general note. C. In the title block. D. None of the above—it is a reference dimension.
16. A practice that eliminates numerous dimension and extension lines, as well as arrows, yet effectively describes the object, is referred to as _____ dimensioning without dimension lines.
    
17. True or False? If a dimension needs to communicate both inch and metric distances, one of the values must be given in a table.
      A. True B. False
18. What type of note uses a leader line?
    
19. What is the name of the ASME standard that sets forth guidelines for including size information with a 3D model, perhaps in conjunction with 2D views?
      A. Undimensioned Drawings. B. Geometric Dimensioning and Tolerancing. C. Digital Product Definition Data Practices. D. Orthographic and Pictorial Views.
20. True or False? There are objects such as printed circuit boards, wire harnesses, or parts with irregular contours that may need to be checked with full size templates or overlays, rather than dimensions from a drawing.
      A. True B. False
