In this first chapter we will cover how to interpret the meaning of the various lines, references, sections and the general layout of construction drawings. Two things to understand here are: Does the drawing covey what I want to be built/ created? The gridlines should be dimensioned on only one discipline, all others will show the gridlines and not the dimensions to avoid any discrepancy. The number of details that must be included in a complete set of blueprints is so large that architects reduce the information on the drawings to a set of standardized symbols and abbreviations in order to make the drawing easier to read and less cluttered. Fig.5: The above drawing uses dashed lines in order to represent the electric circuit lines, upper cabinets in the kitchen as well as the dishwasher, Fig.6: Drawing showing the use of dimension lines and the extension lines, Fig.7: The sample figure showing the use of leader lines to explain the footing and the wall details, Fig.8: Use of short and long break lines in structural drawings, Fig.9.
