What is CAD?

CAD stands for Computer Aided Design. It is basically using computer technology to help people doing design. The design could range from mechanical and machinery industry, product design, up to architectural design.

CAD software was first introduced on 1980s, where computer started to advance. It quickly replaces hand-design which has a lot of drawbacks and is very messy. CAD software improves the efficiency of design process significantly. At this age, almost all designs is done through CAD as computing cost has decreased significantly over the past ten years.

While a lot people think that CAD is referring to 3D modelling, CAD actually refers to both 2D and 3D design. For most cases, 3D modelling is preferred compared to 2D design as 2D design requires higher skills to analyze the design. However, 2D design is still more favorable on some applications. For example, drawing schematic layout and diagrams.

Below is some screenshots of CAD modelling, both 2D and 3D designs ranging from very simple design until  more complex modelling.

Looking at all the pictures above, do you feel like learning CAD modelling? Afraid not as CAD modelling is not difficult. In the following post I'm going to post the basic of CAD modelling and some "Tips and Tricks".
