CAD (Computer-Aided Design) is a computer-based software used to create and edit technical drawings. It’s a crucial tool in various industries, including architecture, engineering, and manufacturing. CAD software allows professionals to design and create 2D and 3D models of products, structures, or systems.

2D Drawings:

  • Blueprints: Detailed plans of buildings, structures, or systems.
  • Floor plans: Layouts of rooms, spaces, and furniture arrangements.
  • Elevations: Views of a building or structure from different sides.
  • Sections: Cuts through a building or structure to show internal details.

3D Models:

  • Wireframe models: Basic representations of objects with edges and vertices.
  • Surface models: Models with a defined surface appearance, often used for visualization.
  • Solid models: Models that represent objects as solid volumes, allowing for accurate mass and volume calculations.

Technical Illustrations:

  • Assembly drawings: Show how parts fit together to form a complete product.
  • Detail drawings: Close-up views of specific components or features.
  • Exploded views: Show how components are assembled or disassembled.
