What is scale?Show answer
Drawings are smaller than the real building, so they are drawn to a scale.
What are dimensions?Show answer
Dimensions are the measurements written on a drawing so the exact size is known without measuring the paper. They are usually given in millimetres on construction drawings (for example 2400 means 2400 mm). Dimensions are essential because paper can stretch or be copied at the wrong size, so the written dimension always takes priority over a measured one.
What are symbols?Show answer
Standard symbols represent common features so drawings stay clear and consistent. Examples include symbols for doors (a line with an arc showing the swing), windows, stairs (a series of lines with an arrow showing the direction up), sanitary fittings (WC, basin, bath), and electrical points (sockets and switches). North is shown by a north point arrow.
