What is CAD software?
CAD, or computer-aided design and drafting (CADD), is technology for design and technical documentation, which replaces manual drafting with an automated process.
If you are a designer, drafter, architect or engineer, you have probably used 2D or 3D CAD programs such as AutoCAD or AutoCAD LT software. These widely used software programs can help you draft construction documentation, explore design ideas, visualise concepts through photorealistic renderings and simulate how a design performs in the real world.

Frequently asked questions (FAQ)
-
Why is CAD software better than drawing by hand? CAD software allows the user to include precise dimensions in their drawings. When designing in CAD, it is also much more efficient to make updates to a drawing and it streamlines the file sharing process.
-
What are the advantages of CAD software? CAD software like AutoCAD provides many advantages including:
- Increased accuracy for drawing precise dimensions
- Automating common processes
- Access to libraries of routinely used items such as doors, windows, and manufacturing parts
- Ability to quickly adjust parts of a drawing without needing to start over
- Managing complex designs details all within one file
- Creating blocks for frequently drawn items
- Increased collaboration with colleagues through the ability to share and mark the same file
-
Who uses CAD software? CAD software is used by many different professions including architects, mechanical engineers, electrical engineers, interior designers, civil engineers, landscape architects, industrial designers, P&ID designers, plant engineers, piping designers, MEP engineers, surveyors, urban planners, and GIS specialists.
