"Great customer service. The folks at Novedge were super helpful in navigating a somewhat complicated order including software upgrades and serial numbers in various stages of inactivity. They were friendly and helpful throughout the process.."
Ruben Ruckmark
"Quick & very helpful. We have been using Novedge for years and are very happy with their quick service when we need to make a purchase and excellent support resolving any issues."
Will Woodson
"Scott is the best. He reminds me about subscriptions dates, guides me in the correct direction for updates. He always responds promptly to me. He is literally the reason I continue to work with Novedge and will do so in the future."
Edward Mchugh
"Calvin Lok is “the man”. After my purchase of Sketchup 2021, he called me and provided step-by-step instructions to ease me through difficulties I was having with the setup of my new software."

Overview
Linux, an open-source operating system created by Linus Torvalds in 1991, has become a cornerstone in the open-source community. Its flexibility, stability, and cost-effectiveness have fueled its adoption across various domains, including software development, servers, and personal computing. Similarly, Computer-Aided Design (CAD) software plays a critical role in numerous industries, from architecture and engineering to automotive and aerospace, enabling professionals to create detailed 2D and 3D models.
Purpose and Scope
The aim of this article is to explore how Linux has significantly influenced the development of open-source CAD software. We will delve into the historical context of both Linux and early CAD systems, examine specific open-source CAD projects that have flourished under Linux, and discuss the contributions from the community. Finally, we will consider the future trajectory of open-source CAD on Linux.
Early Days of Linux
The story of Linux begins with Linus Torvalds, a Finnish computer science student who, in 1991, released the Linux kernel. Torvalds was motivated by a desire to create a free operating system kernel that anyone could modify and distribute. This philosophy of open-source software, where the source code is freely available for anyone to view, modify, and improve, quickly gained traction in the software development community. By the mid-1990s, Linux had evolved into a robust operating system supported by a growing community of developers.
Parallel Developments in CAD
Simultaneously, the field of CAD was making strides. One of the earliest milestones was Ivan Sutherland's development of Sketchpad in 1963, a pioneering interactive graphics program. However, early CAD systems were largely proprietary, expensive, and limited to specialized hardware. Companies like Autodesk and Dassault Systèmes dominated the market with commercial solutions like AutoCAD and CATIA, respectively. Despite their capabilities, these proprietary systems posed significant barriers in terms of cost and accessibility.
The Advantages of Linux
Linux's rise offered numerous advantages that have directly impacted the development of open-source CAD software. Firstly, Linux's inherent stability and flexibility make it an ideal platform for running demanding applications. Its open-source nature means that developers can easily modify the operating system to suit their specific needs, leading to a highly customized and efficient environment for CAD software.
Moreover, Linux's cost-effectiveness is a significant factor. Unlike proprietary operating systems, Linux is free to use, making it an attractive option for small businesses, educational institutions, and individual developers. The vast community of developers and users also contributes to a rich ecosystem of support and collaboration, facilitating the rapid development and improvement of CAD software.
Key Open-Source CAD Projects
Several open-source CAD projects have thrived under the Linux ecosystem, each contributing to the field in unique ways.
Case Study: The FreeCAD Community
The FreeCAD community illustrates the power of collective contributions in open-source projects. Users from around the world participate in forums, contribute code, and develop new features and modules. The collaborative nature of the FreeCAD community has led to significant advancements and continuous improvements in the software.
Case Study: The Role of Linux Distributions
Linux distributions like Ubuntu, Fedora, and Debian have played a vital role in supporting CAD software. These distributions package and maintain CAD applications, making it easy for users to install and update the software. The integration of CAD software into popular Linux distributions has enhanced accessibility and usability for a broader audience.
Influential Figures and Organizations
Key developers and organizations have been instrumental in driving open-source CAD efforts. Individuals like Yorik van Havre, a core developer of FreeCAD, and organizations such as the Free Software Foundation (FSF) and the Open Design Alliance (ODA) have significantly contributed to the advancement of open-source CAD. Additionally, universities and research labs often support and promote open-source CAD projects, furthering innovation and development.
Current Trends
Recent advancements in open-source CAD software include the integration of cloud-based solutions and the incorporation of artificial intelligence (AI) for design automation. Linux continues to support these innovations, providing a robust and adaptable platform for cutting-edge developments.
Challenges and Opportunities
Despite the progress, challenges remain, such as ensuring interoperability with proprietary software and securing funding for ongoing development. However, there are numerous opportunities for growth, including increased adoption in educational settings, small businesses, and the maker community. The open-source nature of these projects fosters a spirit of collaboration and knowledge sharing, which is essential for overcoming obstacles and driving future advancements.
Final Thoughts
Linux has had a transformative influence on the development of open-source CAD software. Its stability, flexibility, and cost-effectiveness have enabled the growth of projects like BRL-CAD, FreeCAD, and OpenSCAD. The collaborative efforts of the community and support from Linux distributions have further propelled these projects. As we look to the future, the potential for continued innovation and collaboration in open-source CAD on Linux remains strong, promising exciting advancements in the years to come.
