maintain. They have been replaced by reliable, large

format inkjet ‘plotters’ which use the same technology as

A4 inkjet printers.

Daisy-wheel and dot-matrix printers have now

been replaced with high resolution laser and inkjet

printers, equally capable of producing text

documents, colour photographs, 3D photo-realistic

images and drawings. The terms ‘printing’ and

‘plotting’ now refer as much to size as to printing

method. The terms are becoming interchangeable in

common usage.

Symbols A set of symbols designed so that they act

as if they were a single entity in the same way a block is

defined. For example, the symbol for a light fitting. Like

blocks, they are then ‘inserted’ into plans as many times

as is needed. Generally, symbols can be inserted at any

scale, to make them bigger or smaller on the plotted

drawing.
