一、 概述

AVEVA 12.1支持CSG接口用于输出几何模型数据。

二、 示例代码

1 DbElement ce = CurrentElement.Element; 2 Aveva.Pdms.CSG.Implementation.CSGTreeBuilderImpl.Init(); 3 Aveva.Pdms.CSG.Implementation.CSGTreeBuilderOptionsImpl op = (Aveva.Pdms.CSG.Implementation.CSGTreeBuilderOptionsImpl)Aveva.Pdms.CSG.Implementation.CSGTreeBuilderImpl.Instance.CreateCSGTreeBuilderOptions(); 4 op.CenterLine = false; 5 op.Holes = false; 6 op.Level = 6; 7 op.SolidOnly = true; 8 op.Tube = true; 9 CSGTree[] tree = Aveva.Pdms.CSG.Implementation.CSGTreeBuilderImpl.Instance.GetGeometry(ce, op);10 for (int a = 0; a < tree.Length; a++)11 {12     for (int b = 0; b < tree[a].Items.Length; b++)13     {14         string Command;15         Aveva.Pdms.Utilities.CommandLine.Command cmd;16         switch (tree[a].Items[b].Type)17         {18             case CSGType.CSG_BOX:19                 CSGBox box = tree[a].Items[b] as CSGBox;20                 double x = box.XLength;21                 double y = box.YLength;22                 double z = box.ZLength;23                 System.Console.WriteLine("CSGBox x:{0} y:{1} z:{2}", x, y, z);24                 break;25             case CSGType.CSG_CYLI:26                 CSGCylinder cylinder = tree[a].Items[b] as CSGCylinder;27                 double radius = cylinder.Radius;28                 double height = cylinder.Height;29                 System.Console.WriteLine("CSGCylinder radius:{0} height:{1}", radius, height);  30                 break;31                 .............................................. 32                     .............................................. 33                 ..............................................  34             default:35                 break;36         }37 38     }39 }

三、总结

通过CSG接口我们可以直接从PDMS中有选择性的抽取PDMS三维模型数据到其他软件。通过编程的方式操作更加灵活，而无需使用rvm格式文件。

特别适合需要做数字化移交时的模型输出开发。
