Engineering CAD

Welcome to Engineering CAD! In this event, teams will read a set of engineering drawings and collaborate to CAD parts in Onshape and then incorporate these parts with provided components to create an assembly.

The information below should not be interpreted as an extension of the rules. You can find free online copies of the current rules for download on the 2026 Rules page of the Science Olympiad website. The official rules in the current Rules Manual take precedence.
