What It Means

Computer-Aided Design (CAD) is the use of software to create precise 2D drawings and 3D models for architectural, engineering, and construction projects. CAD replaces manual drafting with digital tools that increase speed, accuracy, and flexibility in design workflows.

Why It Matters

CAD is foundational in the design process. It enables faster iterations, standardized documentation, and accurate detailing across disciplines. CAD drawings serve as the basis for construction documents, fabrication, and integration with advanced modeling tools like BIM.

Best Practices

• Establish layer and naming standards for consistency across files.
• Use object snaps and parametric constraints to maintain precision.
• Regularly update templates and title blocks for efficiency.
• Export CAD files into BIM software for further collaboration and analysis.
  
  

Real-World Use

An architecture firm uses CAD to draft detailed floor plans and elevations, which are then shared with structural and MEP engineers. These CAD files feed into BIM for coordination, ensuring design intent carries through all project phases.

In Simple Terms

CAD is the digital evolution of the drafting table. It lets you draw, edit, and share building plans quickly—ensuring everyone’s working from the same, accurate blueprint.
