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  


Blueprint 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.
