In these slides, I've given an introduction to computer aided drawing (CAD), discussed its purpose & benefits, listed some of the commonly used CAD software and briefly introduced AutoCAD.

1. COMPUTER AIDED DRAWING
- Rohan Dasgupta

2. Computer Aided Drawing (CAD)
■ Use of computer based software for drawing
■ Frequently used by architects, civil engineers etc.
■ Used to create two-dimensional (2D) and three-dimensional (3D) drawings
■ Output comes in the form of electronic files
■ CAD files be printed and used for construction purposes

3. Purpose of CAD
– optimise and streamline the designers’ workflow
– enhance the quality of design
– improve the level of detailing of the drawing
– make editing easier
– improve documentation

4. Benefits of CAD
• Lower production costs for designs;
• Quicker project completion due to efficient workflow and design process;
• Changes can be made independent of other design details, without the need to
completely re-do a sketch;
• Higher quality designs with documentation (such as angles, measurements, presets)
built into the file;
• Clearer designs, better legibility and ease of interpretation by collaborators, as
handmade drawings are not as clear or detailed;
• Use of digital files can make collaborating with colleagues more simple; and
• Software features can support generative design, solid modeling, and other
technical functions.

5. Commonly used CAD software
• AutoCAD
• Revit
• ArchiCAD
• Civil 3D
• 3DS Max
