摘要

本研究调查了工程设计人员根据技术图纸中的两种投影(等距投影和正投影)建模时的 CAD 性能差异。研究结果表明,在正确复制部件尺寸和形状的百分比方面存在显著差异,这表明在根据正投影生成 CAD 模型时,CAD 效果更好。此外,对持续时间以及草图实体、草图关系和 CAD 特征的数量和类型进行的比较显示,两种情况下的 CAD 建模过程相似。

Engineering designers’ CAD performance when modelling from isometric and orthographic projections
The presented study investigates differences in engineering designers' CAD performance when modelling from two types of projections in technical drawings – isometric and orthographic. The results revealed significant differences in the percentage of correctly replicated components' size and shape, indicating better CAD outcomes when generating CAD models from the orthographic projection. In addition, a comparison of duration, as well as the number and type of sketch entities, sketch relations, and CAD features, showed that CAD modelling processes were similar in both conditions.
