通常，使用GEANT 4模拟的几何体部分已经存在CAD模型。然而，将这些CAD模型直接导入GEANT 4可能是不可能的，并且复杂的组件可能难以通过其他方式定义。其他人已经提出了允许用户解决GEANT 4工具包中加载预定义CAD几何图形的有限支持的解决方案，但是这些解决方案需要使用商业软件进行中间文件格式转换。在这里，我们描述了一种技术，允许CAD模型直接加载为几何图形，而不需要商业软件和中间文件格式转换。使用一组不同复杂度的CAD模型测试了界面的鲁棒性;对于测试中使用的模型，未报告导入错误，并且发现GEANT 4可导航所有几何结构。
Often CAD models already exist for parts of a geometry being simulated using GEANT4. Direct import of these CAD models into GEANT4 however, may not be possible and complex components may be difficult to define via other means. Solutions that allow for users to work around the limited support in the GEANT4 toolkit for loading predefined CAD geometries have been presented by others, however these solutions require intermediate file format conversion using commercial software. Here within we describe a technique that allows for CAD models to be directly loaded as geometry without the need for commercial software and intermediate file format conversion. Robustness of the interface was tested using a set of CAD models of various complexity; for the models used in testing, no import errors were reported and all geometry was found to be navigable by GEANT4.
