在这项研究中，我们实验性地评估了两个GUI原型（命名为“分裂”和“集成”）的参数化CAD建模。研究中的参与者被要求使用两个界面执行一些3D模型理解任务。任务本身分为三类：参数化，拓扑和几何任务。我们测量了两个界面的任务完成时间、错误率和用户满意度。实验结果表明，在所有感兴趣的情况下，当使用“分割”界面时，任务完成时间显着缩短：1）任务作为一个整体，2）按任务类型查看任务。两个界面之间的错误率没有显著差异;然而，参数化任务的错误率明显更高（两个界面）。“拆分”界面的用户满意度明显更高。这项研究让我们更好地了解人类的表现时，感知和理解参数化CAD模型，并提供了深入了解两个研究接口的可用性方面，我们也相信，所获得的知识可以是实用的参数化CAD建模包的实施者。
In this study, we experimentally evaluated two GUI prototypes (named "split" and "integrated") for parametric CAD modeling. Participants in the study were asked to perform a number of 3D model comprehension tasks, using both interfaces. The tasks themselves were classified into three classes: parameterization, topological and geometrical tasks. We measured the task completion times, error rates, and user satisfaction for both interfaces. The experimental results showed that task completion times are significantly shorter when the "split" interface is being used, in all cases of interest: 1) tasks taken as a whole and 2) tasks viewed by task type. There was no significant difference in error rates between the two interfaces; however, error rate was significantly higher in the case of parameterization tasks (for both interfaces). User satisfaction was significantly higher for the "split" interface. The study gave us a better understanding of the human performance when perceiving and comprehending parametric CAD models, and offered insight into the usability aspects of the two studied interfaces; we also believe that the knowledge obtained could be of practical utility to implementers of parametric CAD modeling packages.
