Adding a property set programmatically using OMF

By Katsuaki Takamizawa

Issue:

Using the command _AecPropertyDataEdit and Add button, we can add a property set to an AEC object. How can I do this programmatically in OMF?

Solution:

The property set object is added to AEC object’s extension dictionary named “AEC_PROPERTY_SETS”. Its name will be anonymous (starting with “*”). In order to create it correctly, a property set definition must be referenced, as in the UI. The latter is stored in the dictionary “AEC_PROPERTY_SET_DEFS” under AutoCAD Named Object Dictionary). The following code shows exactly how to do it.

  // get working database
  Acad::ErrorStatus es;
  AcDbDatabase *pCurDb = acdbHostApplicationServices()->workingDatabase();
  if(pCurDb == NULL)
    return;

  // get a property set definition name, e.g. Door, Frame, etc.
  AecUiPrString promptStr(_T(“Input property set definition name”), Adesk::kFalse);
  if(promptStr.go() != AecUiPr::kOk)
    return;

  // get dictionary of property set definition
  AecDictPropertySetDef dictPropSet(pCurDb);
  if( !dictPropSet.isValid() )
  {
    acutPrintf(_T(“nCan not find any property set definitions.”));
    return;
  }

  // get the specific PropSetDef Id
  AcDbObjectId objId;
  es = dictPropSet.getAt(promptStr.value(), objId);
  if( es != Acad::eOk )
  {
    acutPrintf(_T(“nThe %s property set does not exist.”),
      promptStr.value());
    return;
  }

  // select a door
  AecUiPrEntity promptEnt(_T(“Select an Door”), NULL);
  promptEnt.addAllowedClass(AecDbDoor::desc());
  if(promptEnt.go() != AecUiPr::kOk)
  {
    acutPrintf(_T(“nI am only able to work on AEC entities. :-(“));
    return;
  }

  // open the door for write
  AecDbDoor *pEnt;
  es = AecDbDoor::open(pEnt, promptEnt.objectId(), AcDb::kForWrite);
  if(es != Acad::eOk)
  {
    acutPrintf(_T(“nCan not open this AEC entities to write.”));
    return;
  }

  // add property set to door
  es = AecDbPropertySet::addPropertySet(pEnt, objId);
  if(es != Acad::eOk)
  {
    acutPrintf(_T(“nCan not add property set.”));
    return;
  }

  pEnt->close();
