Interscale Content Hub – Computer-Aided Design (CAD) has come an evolution in the past few decades. It’s gone from simple 2D drafting tools to complex 3D modeling systems that are used in many different industries today.
CAD technology lets designers, engineers, and architects create super-accurate drawings, simulations, and models, which helps them work more efficiently and innovate.
It’s used in many different fields, such as architecture, engineering, construction (AEC), automotive, aerospace, and manufacturing.
Knowing how CAD has evolved from 2D to 3D is really useful because it shows us how these tools have changed modern design and what we can expect in the future.
As an example, one of the evolutions of CAD in recent years is the mobile CAD application. You can read about this evolution in “Mobile CAD Applications for Designers on the Go: What We Need to Know.”
So, now it’s time to get into the nuts and bolts to gain a deeper understanding. Let’s get ready to go.
The Origins of CAD: The Early Days
Brian Gott’s “Evolution from 2D to 3D: A Design Engineer’s Perspective,” published by Cambashi Limited in 2003, is a great resource for understanding the historical steps of CAD.
Computer-Aided Design (CAD) got its start in the late 1950s and early 1960s, a time when computers and graphics were getting really sophisticated.
One of the first people to work on CAD was Patrick J. Hanratty, who is often called the “father of CAD.” In 1957, while working at General Electric, Hanratty developed the Pronto system, one of the first numerical control programming languages.
This early work set the stage for the development of CAD systems.
In the early 1960s, Hanratty joined General Motors and developed the DAC (Design Automated by Computer) system, which was one of the first to incorporate responsive visual graphics for design purposes.
Around the same time, Ivan Sutherland, another key figure, developed Sketchpad in 1963 at MIT.
Sketchpad was the first to introduce the concept of graphical interfaces, letting users interact with drawings directly on a screen with a light pen.
These early systems, even though they were limited to 2D capabilities, were pretty groundbreaking and set the stage for future advancements in CAD technology.
The Rise of 2D CAD
The 1980s saw a big shift in CAD technology with the rise of personal computers. During this period, CAD went from being a tool only for big companies with expensive mainframe computers to something more accessible for a wider range of users.
One of the most significant developments was the introduction of AutoCAD by Autodesk in 1982.
AutoCAD was one of the first CAD programs designed for IBM PCs, making it affordable and accessible for smaller firms and individual designers.
AutoCAD and other 2D CAD systems changed the way engineers and architects created and managed drawings.
These systems made it easier to create and modify drawings, and they were more accurate. They also made it easier to store and share design data.
Despite the advantages, these systems were mainly for 2D drafting, so it was still tricky to manage complex spatial relationships and three-dimensional visualization.
The paper “Moving From 2D to 3D CAD: The Productivity and Business Advantages” documents the historical impact and technical advancements of 2D CAD.
We suggest you read the paper for more info about how 2D CAD came about.
The Era of 3D CAD
The 2000s saw the 3D CAD revolution, with the technology being adopted across many industries. It changed the way we design and manufacture things.
In the automotive, aerospace, and construction industries, 3D CAD systems helped make designs more accurate, cut down on mistakes, and let people work together more effectively.
Take Autodesk’s Revit, for instance. It introduced Building Information Modeling (BIM) and totally changed the AEC industry.
Revit lets you create detailed 3D models that combine architectural, structural, and MEP (mechanical, electrical, and plumbing) designs. This makes it easier for stakeholders to work together and avoid conflicts.
PLM systems also integrated CAD with enterprise systems, making the product development process from concept to manufacturing much smoother.
This integration makes it easier for teams to work together and manage data, so they can move between different stages of product development without any hiccups.
The global 3D CAD software market is showing this trend, with lots of growth expected, especially in cloud-based solutions that make it easier to access and work together.

Future Trends in CAD Technology
The future of CAD technology is set to be driven by advancements in artificial intelligence (AI), machine learning (ML), and augmented reality (AR).
We can expect AI and ML to automate repetitive tasks, optimize design processes, and provide predictive analytics, which will free up designers to focus on more creative aspects of their work.
For instance, generative design uses AI algorithms to explore all kinds of design possibilities, coming up with the best solutions based on things like materials, manufacturing methods, and cost.
McKinsey & Company says in “How generative design could reshape the future of product development” that this approach not only speeds up the design process but also reduces material usage and production costs.
Yes, AR and VR will let us experience designs in a whole new way. These technologies let engineers interact with their models in real time, which makes it easier to understand spatial relationships and potential design issues.
For instance, VR can turn 2D CAD models into immersive 3D environments, which makes it easier to visualize and refine designs before physical prototyping.
These new developments will keep making CAD even more useful for designers and engineers.
The combination of these cutting-edge technologies is set to revolutionize the way we design, making everything more efficient, accurate, and collaborative across all industries.
