1. which of the following refers to circulation in a construction drawing?

a. the air flow through the building or structure
b. the general illumination of any space
c. the roads and highways around the structure
d. the physical development of land

1. which of the following is not a true statement about construction drawings?

a. they are always drawn to scale
b. they have the purpose of showing what is being built
c. they describe the locations and dimensions of various construction elements
d. they are always drawn in pen

Explanation:

• Question 7: Dimension lines are specifically used to show the measurements of an object. Center lines show symmetry, section lines show internal features, and break lines show where an object is broken off.
• Question 8: A drafting triangle is used to draw lines at specific angles (e.g., 30°, 45°, 60°). A compass is for drawing circles, a straight - edge for straight lines, and a French curve for irregular curves.
• Question 9: In construction drawing, circulation refers to the movement of people or vehicles, which is related to the roads and highways around the structure. Air flow is ventilation, general illumination is lighting, and physical development of land is land - use planning.
• Question 10: Construction drawings are not always drawn in pen. They can be drawn with pencils (especially during the design process) and then inked (using pens) for final copies. They are drawn to scale, show what is being built, and describe element locations and dimensions.

Answer:

1. C. Dimension lines
2. A. Drafting triangle
3. C. The roads and highways around the structure
4. D. They are always drawn in pen
