When arichitecture offer you an drawing for your new home, you may found out that only for size you can understand, but there also some letters of short words be there.
So here, we explain you the most common use of those words
Construction drawings, also called construction blueprints or plan, are full of abbreviations and acronyms to save space and neaten the overall appearance of the presentation. Remembering all of this shorthand can be tricky, especially when this is added to the challenge of reading all the symbols and deciphering the conventions that might be used by a particular draftsperson or designer.
Fortunately, many blueprint abbreviations have widely accepted meanings and are used in all sorts of blueprints, from framing plans to engineering drawings.
