调用CAD pedit 命令多段线样条曲线化
下面的代码如果注释掉Polyline pline = trans.GetObject(per.ObjectId, OpenMode.ForRead) as Polyline;这句能成功，但是不注释掉这句CAD命令栏提示：错误编辑优化，不理解为什么会这样，向大家请教。#region 多段线样条曲线化
public void pltoSpl()
{
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
using (Transaction trans = db.TransactionManager.StartTransaction())
{
try
{
PromptEntityOptions options = new PromptEntityOptions("");
options.Message = "\n请选择多段线";
options.SetRejectMessage("\n所选择实体不是多段线，请重新选择");
options.AddAllowedClass(typeof(Polyline), true);
PromptEntityResult per = ed.GetEntity(options);
