我想实现cad多行文本的功能,指定多行文本顶端和末端的位置,然后设置字体大小,对齐方式.然后输入要显示的字,高手们这个能指点一下,吗?帮点小忙吧,小弟在次谢过了!

C++的话，AcDbMText，至于C#找一下SDK对应的类，new出来，设置一下参数，加入数据库就行了，应该不难。

谢谢我知道了
Database db = Application.DocumentManager.MdiActiveDocument.Database;
DBTransMan tm = db.TransactionManager;
MText txt = new MText();
txt.Contents = "123\r\n456\r\n测试";
using(Transaction ta = tm.StartTransaction())
{
      BlockTable bt = (BlockTable)tm.GetObject(db.BlockTableId, OpenMode.ForRead);
      ObjectId objid;
      Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
      if (bt.Has("A010001"))
      {
            objid = bt["A010001"];
            BlockTableRecord btr = (BlockTableRecord)tm.GetObject(objid, OpenMode.ForWrite);
            btr.AppendEntity(txt);
            tm.AddNewlyCreatedDBObject(txt, true);
            ed.WriteMessage(btr.Name + " --- Renaud");
            ta.Commit();
      }
      else
      {
            ed.WriteMessage("Not Has --- Renaud");
      }
}
