This study proposes a methodology that would enable a design educator or a design practitioner to optimally select a solid modeling software (solid modeler) for varying objectives. Tasks accomplished to propose the methodology include: (1) reviewing past literature to compile the criteria used for selecting solid modelers, (2) preliminary comparison of a number of solid modelers on established criteria, (3) running designed experiments for comparing the user performance on predetermined solid modeling functions, and (4) compiling the experience gained as a generic methodology. The application was completed over a two-year period while a systematic selection process was undertaken at The Pennsylvania State University (Penn State). This paper documents the entire selection process including the design performance data collected. In addition the performance data, the results of the preliminary preference data are also reported. The set of outcomes of the study is expected to aid companies and design educators in making solid modeler selection decisions.
