摘要
本文提出一种将在国际上广泛应用的AUTOCAD辅助设计与绘图软件包及声线跟踪分析音质的程序加以链接的方法。为此,研制出两个应用程序EXTATTDX及EXTUERTE用来从AUTOCAD建立的设计文件中取出声线跟踪程序所需的信息。本文给出EXTATTDX程序框图并给出一些应用实例。这一链接的成功,不仅加速厅堂音质分析的过程,而且使我们有可能在设计方案阶段及时进行声学评价。
This paper describes a method for lingking the AUTOCAD Drafting Package (' AUTOCAD' ), a well-known computer-aided design software package for architects, with an acoustic rsy-tracing program, in detail, two application programs, EXTATTDX and EXTVERTE, have been worked out to retrieve useful information for a ray-tracing program from the drawing files of AUTOCAD. The flow chart of the EXATTDX progran and some application examples are given. This linking not only speeds up the acoustics analysis process for a variety of halls, but also enables us to test the acoustic properties for buildings at design stage.
