What's 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.
