About the Author

John Biehler has been writing online about technology since 1999. An avid photographer and generally curious geek, he discovered 3D printing a number of years ago and built his first 3D printer shortly thereafter. Since then, he has been actively sharing his knowledge about the technology with thousands of people at various events and conferences in Western Canada and the Pacific Northwest, on television and radio, as well as online through his website. He cofounded a Vancouver-area group of 3D printer builders and enthusiasts that has grown exponentially since it started and as the technology heads toward the mainstream.

Bill Fane was a product engineer and then product engineering manager for Weiser Lock in Vancouver, British Columbia, for 27 years and holds 12 U.S. patents. He has been using AutoCAD for design work since Version 2.17g (1986) and Inventor since version 1.0 beta

(1996). He is a retired Professional Engineer and an Autodesk Authorized Training Centre (ATC) certified instructor. He began teaching mechanical design in 1996 at the British Columbia Institute of Technology (BCIT) in Vancouver, including such courses as AutoCAD,

Mechanical Desktop, Inventor, SolidWorks, machine design, term projects, manufacturing processes, and design procedures. He retired from this position in 2008. He has lectured on a wide range of AutoCAD and Inventor subjects at Autodesk University since 1995 and

at Destination Desktop since 2003. He was the AUGI CAD Camp National Team instructor for the manufacturing track. He has written more than 220 “The Learning Curve” AutoCAD tutorial columns for CADalyst magazine since 1986. He is the current author of the book AutoCAD for Dummies. He also writes software product reviews for CADalyst, Design Product News, and Machine Design. He is an active member of the Vancouver AutoCAD Users Society, “the world’s oldest and most dangerous.” In his spare time he skis, water skis, windsurfs, scuba dives, sails a Hobie Cat, rides an off-road motorcycle, drives his ’37 Rolls Royce limousine or his wife’s ’89 Bentley Turbo R, travels extensively with his wife, and plays with his grandchildren.
