CAD, an acronym for Computer-Aided Design, stands as a powerful digital tool wielded by engineers and designers to craft meticulous 2D drawings and intricate 3D models. In essence, CAD is a virtual drafting board, revolutionising how designs are conceived and transformed. 

From its humble beginnings, CAD has grown into a cornerstone of modern design, reshaping industries such as automotive, architecture, and manufacturing. Its transformative impact lies not only in accelerating the creation of designs but also in fundamentally altering how we conceptualise and bring ideas to life in the digital age.

The Evolution of CAD Software

The roots of CAD software trace back to the mid-20th century when computer-aided drafting systems first emerged. Early systems focused on 2D drafting, laying the groundwork for subsequent advancements. 

Different types of cad software

The 1970s witnessed a leap forward with the introduction of 3D capabilities, heralding a new era in design visualisation. As technology progressed, the distinctions between types of CAD became more defined, offering designers increasingly sophisticated tools.

Different Types of CAD Software

The world of CAD software is teeming with diverse options, each catered to specific needs and design disciplines. Here are some of the most common types of CAD software.


2D CAD software is used to create flat drawings, such as floor plans, schematics, and blueprints. It is the simplest type of CAD software to learn and use and is often used for conceptualising and basic drafting tasks

2D CAD is efficient for projects that don’t require intricate 3D modelling. It’s a stalwart in industries like architecture and electrical design. However, it is limited to representing complex spatial relationships and volumes. So, it may fall short in projects demanding three-dimensional precision.

2.5D CAD

2.5D CAD bridges the gap between 2D and 3D and excels in creating drafts and layouts. It seamlessly integrates with CAM software for CNC machining, enhancing manufacturing processes. While more versatile than 2D, it may lack the depth needed for intricate 3D models, making it less suitable for certain design complexities.


The pinnacle of CAD evolution, 3D CAD offers unparalleled design freedom. More complex than 2D CAD software, it is used to create models of objects in three dimensions. It is more versatile and can be used to create more realistic and detailed models. 

However, 3D CAD software is resource-intensive and potentially overwhelming for simpler projects. It also demands a steeper learning curve and substantial computing power.

CAD Using Neutral File Formats

Emphasising interoperability, neutral file formats like STEP and JT enhance collaboration across various CAD platforms. They ensure compatibility but may sacrifice some specific features. Precision may be compromised when using neutral formats, leading to potential data loss or misinterpretation in intricate designs.

CAD Using Native File Formats

Native file formats encapsulate the full potential of a specific CAD software. They offer comprehensive feature support and functionality. However, they have limited compatibility across different software platforms, requiring users to have the same CAD software for seamless collaboration.
