InsertCopy with selected elements

[BalintBende]

I would like to create a new copy from my original ifc file, but with the selected buildingelements. For this I am using InsertCopy code sample. In my case all Representations and ObjectPlacements are also needed. So I don't want to leave out them from the semantic filter.

IfcStore is my original model which is opened previously, ifcBuildingElements is a List of selected IfcBuildingElements objects.

Here is my semantic filter:

PropertyTranformDelegate semanticFilter = (property, parentObject) => {
if (property.EntityAttribute.Order < 0 &&
            !(property.PropertyInfo.Name == nameof(IIfcProduct.IsDefinedBy) ||
              property.PropertyInfo.Name == nameof(IIfcProduct.IsTypedBy)
              ))
          return null;

        return property.PropertyInfo.GetValue(parentObject, null);
      };

Then I go through my selected building elements and insert to the new model:

using (var iModel = IfcStore.Create(ifcStore.SchemaVersion,
        XbimStoreType.InMemoryModel)) {
        using (var txn = iModel.BeginTransaction("Insert copy")) {
          //single map should be used for all insertions between two models
          var map = new XbimInstanceHandleMap(ifcStore, iModel);

          foreach (var buildingElement in ifcBuildingElements) {
            //insert building element
            iModel.InsertCopy(buildingElement, map,
              semanticFilter, true, false);
          }
          txn.Commit();
        }

This results all building elements not just the selected ones. Could someone help me to fix?
Thank you in advance!
