A Cheat Sheet for Deciphering Architectural Abbreviations and Symbols

Architectural diagrams and drawings such as floor plans, reflected ceiling plans, and elevations are generally pretty self-explanatory, but the intricate details can be quite complex. It can be challenging to decipher the meaning of specific abbreviations or symbols used in these diagrams.

To simplify the process, we have compiled a cheat sheet that outlines many of the commonly used abbreviations and symbols:
