Typhoon – A Roller Coaster Emerges◦Gerstlauer Elektro GmbH a roller coaster

design firm was given six months to design the first version of Euro Fighter. CAD was utilized throughout the entire process replacing paperwork that is no longer feasible in roller coaster design. Over 3000 man hours went into design and production was started in the summer of 2003

Unwind of track - Maximize with left clickThe 3D-layout is a combination of ground view and the unwind of track. It is used to visualize the track layout and does not consist of technical information.

CAD in Entertainment

Forces and dynamic behavior can be determined before a prototype is built

Production can begin directly from data transmitted

Standard parts can be taken from libraries instead of being individually generated

CAD in Manufacturing

Integrated application of CAD/CAM/CAE and RP for rapid development of a humanoid biped robot ◦ The present work concerns the hardware development of a mid-

size humanoid robot, Bonobo, focusing on the use of an integrated application of CAD/CAM/CAE and rapid prototyping (RP) for the rapid development of the robot's outer body parts. Most parts were three-dimensionally designed with 3D CAD, which enables effective connection with CAE analyses, the basis of which lays in kinematic simulation and structural analysis. To reduce the lead time and investment cost of developing parts, RP and CAM are selectively used to manufacture master parts for the body. These master parts are then replicated by using a vacuum casting process, from which we can repeatedly obtain plastic parts. Through this integrated approach, we successfully developed a prototype of Bonobo with a relatively low time and investment cost.
