AutoCad二次开发-插入DWG参照 Teigha库
近日需要运用Oda的teigha库进行不开AutoCad进行dwg地图参照和绑定，查看了SDK终于实现这一需求，故将实现方法分享出来。
using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Text;using System.Threading.Tasks;using Teigha.DatabaseServices;using Teigha.Runtime;namespace HelloTeigha{internal class Program{private static string _desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);static void Main(string[] args){var sourceFile = bine(_desktop, "SourceDwg.dwg");var targetFile = bine(_desktop, "Target.dwg");var Target_tz = bine(_desktop, "AX-04-P03.dwg");using (var service = new Services())using (var database = new Database(false, true)){database.ReadDwgFile(sourceFile, FileOpenMode.OpenForReadAndReadShare, true, "");using (var transaction = database.TransactionManager.StartTransaction())using (var blockTable = database.BlockTableId.GetObject(OpenMode.ForWrite) as BlockTable)using (var modelSpace = blockTable[BlockTableRecord.ModelSpace].GetObject(OpenMode.ForWrite) as BlockTableRecord){try{if (File.Exists(Target_tz)){var referId = database.AttachXref(Target_tz, "AX-04-P03");var blockRefer = new BlockReference(new Teigha.Geometry.Point3d(0, 0, 0), referId);modelSpace.AppendEntity(blockRefer);transaction.AddNewlyCreatedDBObject(blockRefer, true);database.BindXrefs(new ObjectIdCollection() {referId }, true);mit();database.SaveAs(sourceFile, DwgVersion.AC1024);}}catch (System.Exception){}}}}}}
