We have covered the structure of a set of working drawings, the hierarchic progression of location, assembly, component, sub-component drawings, and schedules. We look now at how the drawings themselves are to be prepared, in a form that will be economical of drawing time and will enable multiple copies to be taken for the use of the contractor, sub-contractors, quantity surveyor and others.

Two Examples Of Location Drawings
4.21 Examples of different types of hand lettering CLEAR LETTERING CAN BE PRODUCED AS EASILY AND AS SWIFTLY AS SCRATCHY LETTERS, BY USING THE CORRECT TECHNIQUES Horizontal guidelines are essential unless the draughtsman is very experienced and skilful. They may be drawn lightly in pencil for subsequent erasure when the lettering is in ink or may take the form of a closely gridded sheet laid underneath the tracing paper. The use of a blue pencil for guidelines ensures that they do not appear on...
