| Dimensioning standards in the United States are established by: | ANSI |
| What type of dimensions is when All are read from the bottom of the drawing? | UNIDIRECTIONAL |
| How many times should a hole size be stated on a drawing? | Once |
| A thin line that extends from a note to where it applies is a/an: | Leader line |
| What is the length to width ratio of arrowheads? | 3 : 1 |
| Dimension lines are what line weight? | Thin and dark. |
| The MINIMUM amount of space between a dimension line and the object being dimensioned is: | .375" (10mm) |
| What is the standard length for arrowheads? | .125 (3mm) |
| Leaders and dimension lines most often terminate (end) with a/an: | Arrowhead |

| A thin, solid line extending from a note and terminated with an arrowhead is a/an: | Leader |
| Current dimensioning practices require the DIAMETER symbol be: | A circle with a slash extending through it |
| The dimensioning SYMBOLS for arcs and circles should be given where? | In front of the numerical value |
| When a hole does NOT go fully through the object, you must state its size and: | Depth |
| Avoid dimensioning to: | Hidden lines |
| The MOST important rule in dimensioning is to: | Maintain clarity |
| The size of an ARC is typically specified by its: | Radius |
| CIRCLE SIZE is specified by: | Diameter |
| Dimensions should be placed: | Attached to the view that most clearly describes the part |
| "2X" on a hole note means: | There are two holes the same size |
