如何将一个dwg文件的所有内容都移动到一层上
我想实现一个功能，将dwg文件中的所有内容移动到一层上，然后将这一层的内容导出到一个新的dwg文件中，使用如下代码，但是发现导出的文件还包含了原来dwg文件的所有层！public void Insert2(Data.Directions dir, string fileName)
{
string sTemplatePath = get(get(Autodesk.AutoCAD.ApplicationServices.Application.Preferences, "Files"), "TemplateDwgPath") as string;
string sTemplateFile = sTemplatePath + @"\acadiso.dwt";
string layername = "ImageIdea1" + "_" + dir.ToString() + "_" + Guid.NewGuid();
string sTempFile = sTemplatePath + @"\" + fileName.Substring(fileName.LastIndexOf("\\") + 1); ;
try
{
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
AcDb.Database db = AcDb.HostApplicationServices.WorkingDatabase;
ObjectIdCollection objectids = new ObjectIdCollection();
using (Database FileDatabase = new Database(false, false))
{
FileDatabase.ReadDwgFile(fileName, System.IO.FileShare.Read, false, "");
using (Transaction tr = FileDatabase.TransactionManager.StartTransaction())
{
BlockTable Filebt = FileDatabase.BlockTableId.GetObject(OpenMode.ForWrite) as BlockTable;
BlockTableRecord btrMs =
Filebt.GetObject(OpenMode.ForWrite) as BlockTableRecord;
LayerTable layerTable = (LayerTable)tr.GetObject(FileDatabase.LayerTableId, OpenMode.ForWrite);
CreateNewLayer(tr, layerTable, false, layername);
BlockTableRecordEnumerator symbolTableEnumerator = btrMs.GetEnumerator();
while (symbolTableEnumerator.MoveNext() != false)
{
Entity ent = tr.GetObject(symbolTableEnumerator.Current, OpenMode.ForRead) as Entity;
if (ent.Layer != layername)
{
Entity entcopy = ent.Clone() as Entity;
btrMs.AppendEntity(entcopy);
tr.AddNewlyCreatedDBObject(entcopy, true);
entcopy.Layer = layername;
if (!objectids.Contains(entcopy.ObjectId))
{
objectids.Add(entcopy.ObjectId);
}
}
}
tr.Commit();
}
using (Database sTemplateFileDataBase = new Database(false, true))
{
sTemplateFileDataBase.ReadDwgFile(sTemplateFile, System.IO.FileShare.Read, true, "");
IdMapping map = new IdMapping();
FileDatabase.WblockCloneObjects(
objectids,
SymbolUtilityServices.GetBlockModelSpaceId(sTemplateFileDataBase),
map, DuplicateRecordCloning.Replace, false);
sTemplateFileDataBase.SaveAs(sTempFile, DwgVersion.Current);
}
}
}
catch (System.Exception ex)
{
throw ex;
}
finally
{
try
{
//if (System.IO.File.Exists(sTempFile))
//{
// System.IO.File.Delete(sTempFile);
//}
}
catch (System.Exception ex)
{
throw ex;
}
}
}
static Object get(Object o, string prop)
{
return o.GetType().InvokeMember(prop, System.Reflection.BindingFlags.GetProperty, null, o, null);
}
