1. static void ahlzlARX采用test(void)
2. {
3.     AcDbDatabase* pdb = acdbHostApplicationServices()->workingDatabase();
5.     AcDbBlockTable* pBlockTable;
6.     pdb->getBlockTable(pBlockTable, AcDb::kForRead);
8.     AcDbBlockTableRecord* pBlockTableRecord;
9.     pBlockTable->getAt(ACDB采用MODEL采用SPACE, pBlockTableRecord, AcDb::kForWrite);
11.     AcDbCircle* pEnt = new AcDbCircle(AcGePoint3d(1, 2, 0),AcGeVector3d::kZAxis,6);
12.     AcDbVoidPtrArray curveSegments, regions;
13.     curveSegments.append (pEnt);
14.     AcDbRegion::createFromCurves(curveSegments, regions);
