The students, all enrolled in the Design and Production Drawings course, spent the last four classes in the fall semester designing and building catapults, trebuchets and similar medieval-style throwing devices.

Grouped in teams, students used their CAD skills to design the projects within a 4-foot-by-4-foot-by-4-foot footprint, create a bill of materials, calculate their devices' expected throwing distance, assemble the machines and test the accuracy of their calculations.

The best-designed of the seven devices threw a ball 85 feet across a snowy campus field.

"The students had a great time with it," said Dave Probst, assistant professor of drafting and computer aided design. Students hope to rebuild larger versions of some of their designs in the spring semester.
