AN ANALYSIS OF COMPLEXITY METRICS IN COMPUTER-AIDED DESIGN AT TEXAS A&M

Abstract

Computer-Aided Design (CAD) is a critical tool in the development of modern products. Companies pride themselves on their employees’ CAD knowledge with respect to the products they are able to model. It is important that educators make an effort to understand what students find difficult with regards to modeling, in order to help better teach CAD. Currently, there are a few complexity metrics found in literature such as the part volume ratio, sphere ratio or area ratio. This work will investigate the three ratios above as they apply to a complexity survey of 10 shapes given to students. This work will focus on finding which complexity metric most similarly correlates to the responses of students at Texas A&M University.
