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,pt1,pt1); 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 < numObjs; i++) { es = acdbOpenAcDbEntity(pEnt, dbObjIds, AcDb::kForWrite); if (es == Acad::eOk) { pEnt->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.set(m_d/2,0); vertexPts.set(0,m_d/2); vertexPts.set(0,0); vertexPts.set(m_d/2,0); vertexBulges.setPhysicalLength(0).setLogicalLength(4); vertexBulges = 0.414; vertexBulges = 0; vertexBulges = 0; vertexBulges = 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
