关于AcDbHatch的问题？

我是一个初学者，请各位帮我看一下，下面是画一个园，然后填充，程序编译通过，但运行时没有填充出来。
void test()
{
   ads_point pt1;

   if(ads_getpoint(NULL,"\n请输入插入点：",pt1)!=RTNORM) return;
AcGePoint3d basePoint(pt1[0],pt1[1],pt1[2]);
AcDbCircle *pCircle=new AcDbCircle;
pCircle->setCenter(basePoint);
pCircle->setRadius(1.5);
pCircle->setColorIndex(1); AcDbHatch* pHatch = new AcDbHatch();
   AcGeVector3d normal(0.0, 0.0, 1.0);
   pHatch->setNormal(normal);
   pHatch->setElevation(0.0);
   pHatch->setAssociative(Adesk::kTrue);
pHatch->setPattern(AcDbHatch::kPreDefined, "SOLID");
   pHatch->setHatchStyle(AcDbHatch::kNormal);

AcDbBlockTable *pBlockTable;
acdbHostApplicationServices()->workingDatabase()->getSymbolTable(pBlockTable,AcDb::kForRead);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
pBlockTable->close();

AcDbObjectId circleId;
   AcDbObjectId hatchId;
AcDbObjectIdArray dbObjIds;
pBlockTableRecord->appendAcDbEntity(circleId,pCircle);
   dbObjIds.setLogicalLength(0);
dbObjIds.append(circleId);

   pHatch->appendLoop(AcDbHatch::kDefault, dbObjIds);
   pHatch->evaluateHatch();
dbObjIds.setLogicalLength(0);
   pHatch->getAssocObjIds(dbObjIds);
   pBlockTableRecord->appendAcDbEntity(hatchId,pHatch);
   pBlockTableRecord->close();

AcDbEntity *pEnt;
int numObjs = dbObjIds.length();
   Acad::ErrorStatus es;
   int i;
for (i = 0; i addPersistentReactor(hatchId);
   pEnt->close();
   }
   }

pCircle->close();
pHatch->close();
}

最好用範圍來畫.
AcDbHatch* pHatch = new AcDbHatch();
AcGeVector3d normal(0.0, 0.0, 1.0);
pHatch->setNormal(normal);
pHatch->setElevation(0.0);
pHatch->setAssociative(Adesk::kFalse);

pHatch->setHatchStyle(AcDbHatch::kNormal);
pHatch->setPatternScale(10.0);
AcGePoint2dArray vertexPts;
AcGeDoubleArray vertexBulges;
vertexPts.setPhysicalLength(0).setLogicalLength(4);
vertexPts[0].set(m_d/2,0);
vertexPts[1].set(0,m_d/2);
vertexPts[2].set(0,0);
vertexPts[3].set(m_d/2,0);
vertexBulges.setPhysicalLength(0).setLogicalLength(4);
vertexBulges[0] = 0.414;
vertexBulges[1] = 0;
vertexBulges[2] = 0;
vertexBulges[3] = 0;
color.setColorIndex(150);
pHatch->setColor(color);
pHatch->appendLoop(AcDbHatch::kExternal, vertexPts, vertexBulges);
pHatch->setPattern(AcDbHatch::kUserDefined, "SOLID");
代替你畫的部分
