Feature-based translation of computer-aided design (CAD) models allows designers to preserve the modeling history as a series of modeling operations. Modeling operations or features contain information that is required to modify CAD models to create different variants. Conventional formats, including the standard for the exchange of product model data or the initial graphics exchange specification, cannot preserve design intent and only geometric models can be exchanged. As a result, it is not possible to modify these models after their exchange. Macro-parametric approach (MPA) is a method for exchanging feature-based CAD models among heterogeneous CAD systems. TransCAD, a CAD system for inter-CAD translation, is based on this approach. Translators based on MPA were implemented and tested for exchange between two commercial CAD systems. The issues found during the test rallies are reported and analyzed in this work. MPA can be further extended to remaining features and constraints for exchange between commercial CAD systems.

使用宏参数方法的基于特征的CAD模型转换：特征映射，持久命名和约束转换的问题

基于功能的计算机辅助设计（CAD）模型转换可让设计人员将建模历史保存为一系列建模操作。建模操作或特征包含修改CAD模型以创建不同变体所需的信息。包括产品模型数据交换标准或初始图形交换规范在内的常规格式不能保留设计意图，只能交换几何模型。结果，在交换这些模型后将无法对其进行修改。宏参数方法（MPA）是一种用于在异构CAD系统之间交换基于特征的CAD模型的方法。TransCAD是一种用于CAD间转换的CAD系统，它是基于这种方法的。实施并测试了基于MPA的翻译器，以在两个商业CAD系统之间进行交换。在测试集会期间发现的问题将在此工作中进行报告和分析。MPA可以进一步扩展到其余功能和商业CAD系统之间交换的约束。
