As an expert in the field of computer-aided design (CAD), I have witnessed the evolution of CAD software in the aerospace industry, particularly in the design process of Boeing's aircraft. In this article, I will share my insights on the CAD software used by Boeing and how it has revolutionized the way aircraft are designed and manufactured. One of the most notable aircraft developed using CAD software is the Boeing 777. This aircraft was the world's first 100% digitally designed aircraft, thanks to the use of CATIA - a 3D CAD software system created by Dassault Systemes and IBM. This powerful software provided designers with the necessary tools to create a virtual aircraft with precise simulations, allowing for testing, modification, and retesting of thousands of parts without incurring any manufacturing costs. The use of CATIA also enabled Boeing to create an aircraft that was more aerodynamically and structurally efficient, resulting in better fuel economy. This was a significant breakthrough in the aerospace industry, as it allowed for more accurate and efficient design processes. During this time, Boeing suppliers were also transitioning to using CAD software.
Previously, suppliers would receive drawings from Boeing in IGES or STEP format, which they would then convert to CNC (computer numerical control) for manufacturing. However, with the introduction of CATIA, suppliers were now able to receive solid models directly from Boeing, eliminating the need for conversion and streamlining the manufacturing process. As a CAD software provider myself, I was right in the middle of this transition. My company sold Surfcam, a Boolean system similar to CADKEY, which was widely used by Boeing suppliers. With the shift towards CATIA, we saw a decline in the demand for our software, and it became clear that learning CATIA was crucial for suppliers to stay competitive in the market. As an expert, I highly recommend learning a particular type of parametric, feature-based solid modeling software, such as CATIA, as a springboard for other types of software.
This will not only make the transition to new software easier but also open up opportunities for suppliers to work with different clients and industries.
