获取模型空间图纸空间的ObjectId的几种方法

获取模型空间ObjectId的方法：

方法一：

Dim ZcDB As Database = Application.DocumentManager.MdiActiveDocument.Database

Dim ModelSpaceID As ObjectId = SymbolUtilityServices.GetBlockModelSpaceId(ZcDB)

方法二：

Dim ZcDB As Database = Application.DocumentManager.MdiActiveDocument.Database

Dim ZcBLT As BlockTable = DirectCast(ZcTran.GetObject(ZcDB.BlockTableId, OpenMode.ForRead), BlockTable)

Dim ModelSpaceID As ObjectId = ZcBLT(BlockTableRecord.ModelSpace)

方法三：

Dim ZcDB As Database = Application.DocumentManager.MdiActiveDocument.Database

Dim ZcBLT As BlockTable = DirectCast(ZcTran.GetObject(ZcDB.BlockTableId, OpenMode.ForRead), BlockTable)

Dim ModelSpaceID As ObjectId = ZcBLT(“*Model_Space")

获取图纸空间ObjectId的方法：
