在这里插入图片描述

1. 工具类：PromptTool.cs

}

2. Demo测试

 [CommandMethod("PromptDemo")]public void PromptDemo(){Database db = HostApplicationServices.WorkingDatabase;Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;//PromptPointResult ppr =  ed.GetPoint("\n请选择一个点:");//if (ppr.Status == PromptStatus.OK)//{//    Point3d p1 = ppr.Value;//    ppr = ed.GetPoint("\n请选择第二个个点:");//    if (ppr.Status == PromptStatus.OK)//    {//        Point3d p2 = ppr.Value;//        db.AddLineToModelSpace(p1, p2);//    }//}Point3d p1 = new Point3d(0, 0, 0);Point3d p2 = new Point3d();PromptPointOptions ppo = new PromptPointOptions("请指定第一个点:");ppo.AllowNone = true;PromptPointResult ppr = GetPoint(ppo);if (ppr.Status == PromptStatus.Cancel) return;if (ppr.Status == PromptStatus.OK) p1 = ppr.Value;ppo.Message = "请指定第二个点";ppo.BasePoint = p1;ppo.UseBasePoint = true;ppr = GetPoint(ppo);if (ppr.Status == PromptStatus.Cancel) return;if (ppr.Status == PromptStatus.None) return;if (ppr.Status == PromptStatus.OK) p2 = ppr.Value;db.AddLineToModelSpace(p1, p2);}private PromptPointResult GetPoint(PromptPointOptions ppo){ppo.AllowNone = true;Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;return ed.GetPoint(ppo);}
