如何读取图上圆的信息？

• 回答：

  代码实现如下：

  
  

  MrxDbgSelSet ss = new MrxDbgSelSet();
  ss.allSelect();
  for(int i = 0; i <ss.size();i++)
  {
      long lId = ss.at(i);
  
      McDbEntity ent = new McDbEntity (lId);
  
      // 得到对象的层名.
      Log.e("LayerName",ent.layerName());
  
      String sName =  MxFunction.getTypeName(lId);
  
      if(sName.equals("McDbCircle"))
      {
          McDbCircle cir = new McDbCircle(ss.at(i));
      
          McGePoint3d cen = cir.getCenter();
          double fR = cir.getRadius();
      
          String sT;
          sT = String.format("cen:%f,%f,r:%f",cen.x,cen.y,fR);
      
          Log.e("Circledata",sT);
      }
