Blueprint Symbols: Floor Plan, HVAC, Plumbing and Architectural Floor Plan Symbols

Blueprints are a group of symbols. Blueprint symbols are utilized to denote objects, functions, or systems in the plan of engineering drawing.

Blueprint symbols are utilized in architectural drawings, structural drawings, electrical drawings, etc.

  1. Floor Plan Symbols  

In-floor plans we see various types of symbols, it contains furniture, windows, doors, etc. Some major symbols of floor plans are a compass, doors, stairs, windows, walls, and applications.

Compass

It is an arrow symbol that provides an orientation to the building by which the architect or builder can know the north direction. By this symbol, we can easily know the east, west, north, and south directions.

Doors

The door symbol is provided by the straight line and the arc represents the opening projection of the door.

Stairs

It is prepared by parallel lines and is placed between two windows.

Windows

The symbol of a window is drawn by three lines.

Walls

Walls are of two types; interior walls and exterior walls. Both walls are prepared by two parallel lines but exterior wall lines are dark and thick and interior wall lines are light.

Appliances

These are the other symbols in the floor plan such as the bathtub, toilet, sinks, other furniture, etc. All appliance symbols are prepared by single lines.

Some floor plan abbreviations:
