Question

1. gridlines are used to _. a. show changes in topography within a building structure b. indicate that an object has been broken off c. indicate land boundaries on a site plan d. make it easy to refer to specific locations on a plan 8. a dimension is a measurement written as a _. a. range b. number c. letter d. symbol 9. one way that an engineers scale differs from an architectural scale is that the engineers scale _. a. uses fractional values b. is based on units of 10 c. cannot be used to scale long distances d. is only used for drawings of machinery 10. if 1 inch equals 10 feet, the arrow on the engineers scale in the figure above indicates a length. a. 5 feet b. 6 inches c. 50 feet d. 1/2 inch

Explanation:

• For question 7, gridlines are used to easily refer to specific locations on a plan. They are not for showing topography in a building, indicating broken - off objects, or land boundaries.
• For question 8, a dimension is a measurement written as a number. It is not a range, letter, or symbol in the context of basic measurement representation.
• For question 9, an engineer's scale is based on units of 10 while an architectural scale has different fractional values and usage scenarios. It is not limited to machinery drawings and can be used for long - distance scaling.
• For question 10, if 1 inch equals 10 feet, and the arrow on the engineer's scale points to 5 on the scale (assuming it's in inches), then the length is 5×10 = 50 feet.

Answer:

1. d. make it easy to refer to specific locations on a plan
2. b. number
3. b. is based on units of 10
4. c. 50 feet
