摘要:随着BIM概念及技术在国内建筑行业的普及与认可度的提高，同一个建筑模型用于多个软件之间的转换接口的实现成为广大用户一个迫切的需求。基于此，我们开发了PMCAD与Revit和Etabs的模型转换接口，并做了大量工程测试，结果符合工程需求。本文介绍了软件设计的基本架构，并列举了一些实际工程的转换效果、转换前后的计算结果比较等，结果证明P-trans软件可以应用于实际工程。

Abstract: BIM technology is already accepted and popularized in recent years in China, so the transformation of the same building model from one software to another is needed for the users. Based on the requirement, we developed the interface software for Revit and Etabs. Furthermore, we tested many practical projects and got satisfied results. The paper presented the structure of the software, and some transformation results of practical projects. Then we compared the analysis results of one project with its transformation in different software. All the results proved that the P-Trans could be used in projects.
