Piping drawings for large buildings typically use a scale of b. 1:100, while small buildings and houses use a scale of 1:200, and details use a scale of 1:1000.
Step-by-step explanation:
For piping drawings, the scale used for large buildings is typically b. 1:100, the scale used for small buildings and houses is usually 1:200, and the scale used for details is commonly 1:1000.
These scales allow the drawings to accurately represent the actual sizes and dimensions of the pipes in relation to the building or structure being depicted.
