Who Is Michael Riddle?
Michael Riddle is an American software engineer and designer whose work dates back to the late 1970s. At that time, computer-aided design required expensive hardware. However, he believed powerful drafting tools could run on personal computers.
Over time, his career bridged the transition from mainframe computing to affordable desktop systems. Because of this shift, engineering, architecture, and construction workflows across the United States were permanently changed.
Early Career and Technical Background
Riddle began developing CAD software when computing resources were extremely limited. For example, memory was scarce, processors were slow, and displays were basic.
Instead of seeing limitations, he saw design challenges. Consequently, he focused on efficiency, speed, and user control—principles that later defined his work and clearly separated his software from competitors.
The Creation of Interact
In 1979, Michael Riddle developed Interact, one of the first CAD systems designed to run on microcomputers.
At the time, this achievement was groundbreaking. More importantly, Interact proved that complex drafting tasks could be performed without massive computing infrastructure. As a result, it became a key proof-of-concept for future CAD developers.
EasyCAD and the Rise of Affordable Design Tools
Following the success of Interact, Riddle introduced EasyCAD, a lower-cost drafting solution aimed at smaller firms and individual users.
Because of EasyCAD, financial barriers were significantly reduced. Previously, engineers and architects relied on paper drafting or shared systems. Now, they could work digitally from their own offices.
FastCAD: Speed as a Philosophy
Eventually, FastCAD became Michael Riddle’s most recognized creation. As the name suggests, performance was central to its design.
FastCAD was known for:
• Extremely fast screen redraws
• Low hardware requirements
• Precise drafting controls
• Minimal system overhead
Therefore, it became popular with professionals who valued responsiveness and efficiency over flashy features.
Founding Evolution Computing
To support and distribute his software, Riddle founded Evolution Computing in the mid-1980s.
From the beginning, the company focused on:
• Direct relationships with users
• Continuous performance improvements
• Long-term software stability
• Practical, real-world design needs
Because of this user-centric approach, FastCAD developed a loyal and lasting user base.
Influence on Modern CAD Software
Although many modern tools are far more complex, Riddle’s influence remains visible.
In particular, his ideas helped shape:
• Command-driven drafting workflows
• Keyboard-efficient design methods
• Lightweight software architectures
• User-controlled customization
As a result, many principles seen in professional CAD systems today trace back to pioneers like him.
Design Philosophy and Approach
Michael Riddle believed software should adapt to the user, not the other way around. In contrast to many modern trends, he valued simplicity and control.
Specifically, his philosophy emphasized:
• Speed over visual excess
• Precision over automation dependency
• User mastery over hidden processes
• Stability over constant redesign
Consequently, this mindset appealed strongly to experienced professionals.
Interviews and Historical Recognition
Over the years, Riddle has participated in interviews and retrospectives documenting early CAD history.
These accounts highlight:
• The technical constraints of early PCs
• The challenge of writing efficient graphics code
• The cultural shift from drafting tables to screens
• The resistance—and eventual acceptance—of CAD
Therefore, his firsthand perspective remains valuable to computing historians.
Michael Riddle’s Role in CAD Democratization
Perhaps his greatest contribution was accessibility.
By proving CAD could run on affordable machines, Riddle helped:
• Expand digital drafting nationwide
• Reduce reliance on specialized facilities
• Enable small firms to compete
• Accelerate design iteration cycles
Ultimately, this shift reshaped multiple industries.
Common Confusion Around the Name Michael Riddle
It’s worth noting that the name Michael Riddle appears across multiple professions. However, the CAD pioneer is distinct from others in law, medicine, music, or finance.
In most cases, search interest around this keyword connects directly to software history and CAD innovation.
Why Michael Riddle Still Matters Today
Even in 2025, professionals continue to discuss performance, efficiency, and user control—exactly the areas Riddle prioritized decades ago.
In essence, his work reminds modern developers that powerful tools don’t always require massive systems or unnecessary complexity.
