To allow for the efficient reuse of existing CAD models, design intent has to be clearly conveyed in the original design. A modeling and alteration exercise was implemented in a freshman class using NX to assess the CAD modeling procedures of novice CAD users. To analyze the effects of CAD model attributes on alteration time and procedure, the attributes of both the original and altered models were analyzed. A survey was conducted which assessed students! perception of the original models. The analysis data and survey results are presented in this paper. The results show the effects of different incentives on modeling and how the feature selection and organization correlate to proper design intent. This work provided base data for the study to form preferred CAD modeling procedures.
