Lesson 9:Architectural Symbols

Architectural symbols

• Symbols are needed to classify and simplify drawings.
• They are used as substitute symbols for materials and fixtures.
• It is often more convenient and timely to draw a symbol than to repeat a description every time it is used.
• It would be impossible to describe all construction materials without the use of symbols.
• Learning and remembering symbols will be easier if you associate each symbol with the actual material or facility it represents.
• Several symbols must be added to the plan to relate it to the other drawings.
• They are drawn with medium lines.

1. Common symbols used on floor plan
2. Material symbols
3. Architectural graphic symbols
4. Drawing symbols for cross- reference
