Which AutoCAD Symbols and Meanings

Understanding AutoCAD Symbols and Their Significance

What Are AutoCAD Symbols?

AutoCAD symbols are graphic representations found in architectural, electrical, and mechanical drawings. These symbols streamline the design process by allowing designers to represent complex elements efficiently. By understanding what each symbol signifies, one can convey information clearly and effectively within a drawing.

Common AutoCAD Symbols and Their Meanings

1. “At” Symbol (@)

The "at" symbol is frequently used to specify locations or dimensions within drawings. An example of its use is: “MOUNT FIXTURE @ 88" A.F.F.” Here, A.F.F. stands for "above finished floor," indicating the height at which a fixture should be mounted. This symbol is generally referenced in the drawing’s legend for clarity.

2. Electrical Symbols

Electrical symbols are vital for conveying information regarding circuitry, outlets, and lighting. Common symbols include:

• Light Bulb: Indicates light fixtures.
• Switch: Represents a switch connected to an electrical circuit.
• Outlet: Shows where electrical outlets are located.
