From Pencils to Pixels: How CAD Transformed Design
The history of Computer Aided Design and Drafting (CAD) is a fascinating journey that mirrors the evolution of technology itself. In the early days, drafting was a manual process, requiring draftsmen to spend countless hours drawing intricate designs by hand. The drafting table, T-square, and a set of pencils were the primary tools of the trade. While these methods were effective, they were also time-consuming and prone to human error.
Enter the 1960s, a decade that saw the birth of CAD as we know it today. The first CAD software, Sketchpad, was developed by Ivan Sutherland as part of his Ph.D. thesis at MIT. This rudimentary program laid the foundation for future CAD technologies, allowing users to interact with a computer graphically for the first time.
As computing power increased, so did the capabilities of CAD software. By the late 1970s and early 1980s, companies like Autodesk introduced software such as AutoCAD, which became the industry standard. These platforms allowed for 2D and eventually 3D design, bringing an unprecedented level of detail and precision to the field.
Computer aided drafting and design has become an integral part of various industries.

2D or 3D? Parametric or Non-Parametric? Navigating the CAD Landscape
Understanding the types of CAD is crucial for selecting the right tool for your design needs. CAD systems can be broadly categorized into two dimensions: 2D and 3D, and by their design methodology: parametric and non-parametric.
2D vs. 3D
-
2D CAD: This is the most basic form of CAD drafting, often used for drafting and simple designs. It operates on a single plane and is primarily concerned with length and width.
-
3D CAD: This is a more advanced form of CAD design that includes the third dimension: depth. It is used for complex designs and simulations, offering a more realistic representation of objects.
Parametric Design vs. Non-Parametric
-
Parametric Design: In parametric CAD, all elements of the design are interrelated. A change in one parameter automatically updates all related components. This is highly useful for complex, multi-component designs.
-
Non-Parametric: In non-parametric CAD, elements are independent of each other. This offers more flexibility but can be time-consuming for complex designs.
Comparison Chart
| Type | Dimension | Interrelation | Use-Case |
|---|---|---|---|
| 2D | 2D | Either | Drafting, simple designs |
| 3D | 3D | Either | Complex designs, simulations |
| Parametric | Either | Yes | Complex, multi-component designs |
| Non-Parametric | Either | No | Flexible, independent designs |
Understanding these types helps in choosing the right CAD tool for your project, whether it’s a simple 2D sketch or a complex 3D model with interrelated components.
What is the main difference between 2D and 3D CAD?
2D CAD operates on a single plane and is used for simple designs, while 3D CAD includes depth and is used for complex designs and simulations.
How does parametric CAD differ from non-parametric CAD?
