最简单的AcDbHatch

软件架构师何志丹

AcDbObjectId id = CAddEntity().AddCircle(0,0,300);
  AcDbObjectIdArray ids;
  ids.append(id);  AcDbHatch*  hatch = new AcDbHatch();
  hatch->setPattern(AcDbHatch::kPreDefined, _T("HONEY"));
  hatch->setDatabaseDefaults();
     hatch->setAssociative(Adesk::kTrue);    // BUG: doesn't do squat! have to set the reactor yourself to get associativity!
  hatch->setNormal(AcGeVector3d(0,0,1) );
  hatch->appendLoop(AcDbHatch::kExternal,ids);
     hatch->evaluateHatch();    
  CAddEntity().AddEntity(hatch);
  hatch->close();
