1--實體的選擇集
1 PromptEntityOptions entPline = new PromptEntityOptions("選擇一條斷面線："); 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--點的選擇
//選擇斷面零點 PromptPointOptions pointOp = new PromptPointOptions("請選擇斷面零點：\n"); PromptPointResult pointRes = ed.GetPoint(pointOp); if (pointRes.Status == PromptStatus.OK) { // ed.WriteMessage("選擇的零點為：" + pointRes.Value.X.ToString() + pointRes.Value.Y.ToString() + pointRes.Value.Z.ToString()); ed.WriteMessage("選擇的零點為：" + pointRes.Value.ToString()); //斷面零點信息 gcdZERO.GcdX = pointRes.Value.X; gcdZERO.GcdY = pointRes.Value.Y; gcdZERO.GcdH = pointRes.Value.Z; gcdZERO.GcdSCDH = dmCS.DmH + "斷面零點"; gcdDic.Add(gcdZERO);//將高程點也加入到gcdDic中 }
3- 根據過濾器來選擇點
