[求助]遍历图纸空间和模型空间

csharpnice

向大家请教一个问题，我想遍历图纸空间和模型空间，按照一定的条件找出一些entity
下面是我写的代码，发现得到的layout信息并不是读入的dwg文件对应的，不知道是为什么？
在QQ群里呼叫多次，没有解决

2. Database mDatabase = new Database();
3. try
4. {
5. mDatabase.ReadDwgFile(filename, System.IO.FileShare.Read, true, null);
6. using (Transaction tr = mDatabase.TransactionManager.StartTransaction())
7. {
8. BlockTable bt = (BlockTable)tr.GetObject(mDatabase.BlockTableId, OpenMode.ForRead, false);
9. printdata = printdataList.AddFileToPrint(filename);
10. foreach (ObjectId btrId in bt)
11. {
12. BlockTableRecord btr = (BlockTableRecord)tr.GetObject(btrId, OpenMode.ForRead);
13. if (btr.IsLayout) //layoutsToPlot.Add(btId);
14. {
15. Layout lo = (Layout)tr.GetObject(btr.LayoutId, OpenMode.ForRead);
16. LayoutData layoutData = new LayoutData();
17. layoutData.LayoutName = lo.LayoutName;
18. foreach (ObjectId item in btr)
19. {
20. Entity ent = tr.GetObject(item, OpenMode.ForRead) as Entity;
21. if (!EntityIsTuKuang(ent)) continue;
22. Polyline pl = ent as Polyline;
23. Extents3d ext3D = pl.GeometricExtents;
24. Extents2d ext2D = new Extents2d(ext3D.MinPoint.X, ext3D.MinPoint.Y, ext3D.MaxPoint.X, ext3D.MaxPoint.Y);
25. layoutData.WinowAreas.Add(PublicMethod.Ext2DToRange(ext2D));
26. }
27. if (layoutData.WinowAreas.Count != 0)
28. printdata.AddLayoutData(layoutData);
29. }
30. }
31. }
32. dgvAddRow(printdata);
33. }

Database mDatabase = new Database(); try { mDatabase.ReadDwgFile(filename, System.IO.FileShare.Read, true, null); using (Transaction tr = mDatabase.TransactionManager.StartTransaction()) { BlockTable bt = (BlockTable)tr.GetObject(mDatabase.BlockTableId, OpenMode.ForRead, false); printdata = printdataList.AddFileToPrint(filename); foreach (ObjectId btrId in bt) { BlockTableRecord btr = (BlockTableRecord)tr.GetObject(btrId, OpenMode.ForRead); if (btr.IsLayout) //layoutsToPlot.Add(btId); { Layout lo = (Layout)tr.GetObject(btr.LayoutId, OpenMode.ForRead); LayoutData layoutData = new LayoutData(); layoutData.LayoutName = lo.LayoutName; foreach (ObjectId item in btr) { Entity ent = tr.GetObject(item, OpenMode.ForRead) as Entity; if (!EntityIsTuKuang(ent)) continue; Polyline pl = ent as Polyline; Extents3d ext3D = pl.GeometricExtents; Extents2d ext2D = new Extents2d(ext3D.MinPoint.X, ext3D.MinPoint.Y, ext3D.MaxPoint.X, ext3D.MaxPoint.Y); layoutData.WinowAreas.Add(PublicMethod.Ext2DToRange(ext2D)); } if (layoutData.WinowAreas.Count != 0) printdata.AddLayoutData(layoutData); } } } dgvAddRow(printdata); }

打印方面的很少有人弄哈

我是没搞过这东东

csharpnice

上面的代码和打印的关系不大

 

我需要做的就是，读入一个dwg的数据库，然后遍历所有的图纸空间和模型空间。比如说我现在的dwg有两个layout：“model”，“我的布局”，但是通过以上代码得到却不是这两个layout，很奇怪

csharpnice

同样的代码在当前数据库中却有效果，能够得到想要的值

估计你获取的是当前文档的layout？、

试下设置当前数据库？

HostApplicationServices.WorkingDatabase = mDatabase;

记得做完要还原

csharpnice

Database mDatabase = new Database(false,true); OK
