Lập kế hoạch & Dự toánCâu 293 / 360
On a plumbing plan you see three parallel lines each with a different break symbol: a single dash, a dash-dot, and a solid. What is the best way to know which system each represents?
a.Assume the solid line is always gas
b.Read the line-type legend on the plan set
c.Guess based on pipe size
d.Call the fixture manufacturer
Giải thích
Different designers assign line types to systems (waste, vent, water, gas) in the legend, so the legend is the authoritative key for that set. Guessing risks routing the wrong pipe. Always confirm line types and abbreviations against the specific drawing's legend before takeoff or layout.
