A fence section detail shows 'FG' and 'FF' elevations. What do these abbreviations mean?

Accepted Answer

Finished Grade and Finished Floor

Answer

'FG' means Finished Grade (final outdoor ground level) and 'FF' means Finished Floor, both used as elevation reference points.

Question 4

On a fence plan, a bold solid line weight is used for fence panels while a thin line is used for property lines. Why does line weight matter?

Accepted Answer

Line weight differentiates the hierarchy and importance of drawing elements

Answer

Line weight hierarchy helps readers instantly distinguish between primary construction elements, reference lines, and secondary information.
