![]() This assessment could be taken into account when assessing development timelines in academic projects, especially in institutions where sources for licensed CAD software are limited, or for students who want to practise and/or use a CAD apparel prototype system outside institutions’ premises. The present study compares commercial licensed CAD systems for pattern design to an open source software, Seamly2D, and to MacroGen’s Cameo v6 programme which runs within an OSS. ![]() The number of operations is a proxy for the number of features or operations required to create a specific piece of CAD geometry. ![]() ![]() The amount of time required to create a CAD model has been reported and used as a metric for CAD modelling and alteration quality. Johnson, Valverde and Thomison noted that modelling procedure includes the amount of time spent engaging in particular modelling activities. Several other authors have highlighted the likely effects of CAD model complexity. Summers and Shah noted that an objective assessment of CAD model complexity can be useful in assessing case studies, evaluating the results of experiments, or evaluating student projects. With the rapid rise in the use of open source software (OSS) in all types of applications, it is important to know if the existing OSS CAD software for garment prototype development can successfully support the learning process.
