Indexing Symbols

To summarize, when reading symbols on a blueprint, the following should be remembered:

• Placement of symbols on floor plans and elevations may be approximate unless they are dimensioned.

• Do not scale a symbol to determine its size. Specific information should be obtained from relevant details, schedules, or specifications.

• A symbol's size may vary according to the scale of the drawing.

• Symbols drawn to represent surface materials may cover only a representative portion of an area.

• Abbreviations are often used in place of a graphic symbol in order to reduce drawing time and space. A list of architectural/construction abbreviations is given in the Appendix.

• Symbols for the same items are usually different in plan, elevation, and section drawings.

• Some symbols may use the same or similar graphic treatments in elevation. Check notations, detail drawings, and specifications for identification.
