This is a post by Cat McClintock on PTC site.
A few months ago, PTC asked Creo users to submit their best work for a Product Design Contest. Submissions came from more than 60 countries and included objects like a wooden bike, a car that runs on compressed air, and beer bottles—all made with Creo 3D CAD software.
Among the top designs was a handheld power tool that clearly came from the desk of a talented industrial designer. Both sturdy and attractive, Xiyin Yao’s orbital sander looked like something we wanted on our own workbench. So, after we made him one of our finalists in the contest, we asked him to tell us more about his design, inspiration, and any tips he might have for other aspiring contest winners.
