# Electrical Drawing Software and Electrical Symbols

An electrical drawing, is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.

Electrical drawing software will assist you in drawing your electrical diagrams using standard electrical symbols, it minimize efforts and makes it very easy for beginners. Electrical symbols and smart connectors help present your:

- Electronic Circuits
- Automotive Wiring
- Electrical Schematics
- Electrical Wiring
- Cabling Layout Diagrams
- Electrical Layouts
- Circuits and Logic Schematics
- Logic Gate Diagrams
- Blue Prints
- Digital Circuits
- Parallel Circuits

ConceptDraw DIAGRAM is a powerful software for creating professional looking electrical circuits quick and easy. For this purpose you can use the Electrical Engineering solution from the "Engineering" area of ConceptDraw Solution Park, it include thousands of electrical symbols.
