[ARX]求助 块的制作出现问题

fazi

以下是我的程序：程序实现（1）makeablock制作一个块 块包含的实体自己选定（2）printall 显示刚才制作的块的一些特性

问题：为什么特性不能显示？

void ccfch1makeablock()
{
 // TODO: Implement the command
  AcDbBlockTableRecord *precord=new AcDbBlockTableRecord();
   char blockname[10];
   acedGetString(NULL,"\n输入块的名字",blockname);
   precord->setName(blockname);//"ASDK-NO-ATT"
   AcDbBlockTable *ptable;
   AcDbObjectId recordId;
   acdbHostApplicationServices()->workingDatabase()->getBlockTable(ptable,AcDb::kForWrite);
   ptable->add(recordId,precord);
   ptable->close();
  ads_name entname,entn;
   long len;
   AcDbObjectId pentId,pId;
   AcDbEntity *pent;
   acedSSGet(NULL,NULL,NULL,NULL,entname);
   acedSSLength(entname,&len);
   for(int i=0;i<len;i++)
   {
     acedSSName(entname,i,entn);
  acdbGetObjectId(pentId,entn);
  acdbOpenAcDbEntity(pent,pentId,AcDb::kForRead);
  precord->appendAcDbEntity(pId,pent);
  pent->close();
   }
   precord->close();
   acedSSFree(entname);
   acutPrintf("\n块操作完成");
}

是不是应该把const char *pCname = pEntity->isA()->name();的const去掉?

不是 因为 for (pBlockIterator->start(); !pBlockIterator->done(); pBlockIterator->step())这个循环进不去，块浏览器根本没有发现实体
