SAN RAFAEL, Calif., March 28 /PRNewswire-FirstCall/ -- Autodesk, Inc. (Nasdaq: ADSK) today announced that Columbia Aircraft Manufacturing Corporation, the maker of the world's fastest certified piston-powered aircraft, was named Autodesk's Inventor of the Month for March 2006. The program recognizes the most innovative design and engineering advancements made by the extensive community of customers using Autodesk Inventor software, the world's best-selling 3D mechanical design software and best choice for AutoCAD software users.

Based in Bend, Oregon, the Columbia Aircraft Manufacturing Corporation is wholly focused on building a line of personal aircraft that redefine aircraft performance and pilot expectations. Columbia places a premium on engineering and design to produce the best looking and best performing general aviation aircraft in the world. The company's flagship product, the Columbia 400, holds the title of World's Fastest Certified, Piston-Powered Aircraft. No other single or twin engine, fixed or retractable gear aircraft can match the performance.

Working with Autodesk partner IMAGINiT Technologies, a leading provider of CAD/CAM/CAE solutions to the manufacturing industry, Columbia has used Autodesk Inventor software across many areas in the company's design processes. "We take Autodesk Inventor to the limits, and it continues to deliver," said Kurt Nichols, Engineering Manager at Columbia Aircraft, and part of the team responsible for developing the company's award winning planes. "The depth of detail captured in the 3D models makes it much easier for us to reduce design cycles while raising quality. That helps us deliver on the types of aviation technology innovations that our customer base has come to expect from us -- whether it's a new type of fuselage bonding fixture or improved nose landing gear."

Additionally, Autodesk Inventor's 3D models help ensure that Columbia's aircraft meet the highest possible safety standards. Columbia is able to test out its designs under real-world conditions by exporting Autodesk Inventor models to a finite element analysis program, and based on the results can make adjustments to the model as needed -- all before an actual physical prototype is built. It's no wonder that Columbia aircraft are the only modern aircraft on the market that meet the strict Utility Category certification -- the highest non-aerobatic FAA certification level.

"Columbia Aircraft demonstrates how the manufacturing industry has embraced Autodesk Inventor as a way to streamline the design process while improving the end product," said Robert "Buzz" Kross, vice president of Autodesk Manufacturing Solutions Division. "We are pleased to name them as our March Inventor of the Month."
