1--实体的选择集
1 PromptEntityOptions entPline = new PromptEntityOptions("选择一条断面线："); 2 PromptEntityResult entPlineRes = ed.GetEntity(entPline); 3 4 if (entPlineRes.Status == PromptStatus.OK) 5 { 6 Polyline entpolyline = (Polyline)trans.GetObject(entPlineRes.ObjectId, OpenMode.ForRead); 7 //ed.WriteMessage(entpolyline.EndPoint.ToString() + entpolyline.StartPoint.ToString()); 8 polylineStartPoint = entpolyline.StartPoint; 9 polylineEndPoint = entpolyline.EndPoint; 10 }
2--点的选择
//选择断面零点 PromptPointOptions pointOp = new PromptPointOptions("请选择断面零点：\n"); PromptPointResult pointRes = ed.GetPoint(pointOp); if (pointRes.Status == PromptStatus.OK) { // ed.WriteMessage("选择的零点为：" + pointRes.Value.X.ToString() + pointRes.Value.Y.ToString() + pointRes.Value.Z.ToString()); ed.WriteMessage("选择的零点为：" + pointRes.Value.ToString()); //断面零点信息 gcdZERO.GcdX = pointRes.Value.X; gcdZERO.GcdY = pointRes.Value.Y; gcdZERO.GcdH = pointRes.Value.Z; gcdZERO.GcdSCDH = dmCS.DmH + "断面零点"; gcdDic.Add(gcdZERO);//将高程点也加入到gcdDic中 }
3- 根据过滤器来选择点
