Hello,

You can use the logical filter to union those electrical related category filters. And then get all those elements list from the FilteredElementCollector.

The steps is like this. I didnot test the code. Replace the right category here in the first couple of lines.

<code>

public IList<Element> GetElectricalElements(Document doc)

{

   ElementCategoryFilter catFilter1 = new ElementCategoryFilter(BuiltInCategory.OST****);

   ElementCategoryFilter catFilter2 = new ElementCategoryFilter(BuiltInCategory.OST****);

   ElementCategoryFilter catFilter3 = new ElementCategoryFilter(BuiltInCategory.OST****);

   ElementCategoryFilter catFilter4 = new ElementCategoryFilter(BuiltInCategory.OST****);

   ElementCategoryFilter catFilter5 = new ElementCategoryFilter(BuiltInCategory.OST****);

    //create more filter here as needed.

   IList<ElementFilter> list = New List<ElementFilter>();

   list.Add(catFilter1);

   list.Add(catFilter2);

   list.Add(catFilter3);

   list.Add(catFilter4);

   list.Add(catFilter5);

  //add more to the list here.

   LogicalOrFilter orFilter = new LogicalOrFilter(list);

    FilterElementCollector collector  = new FilterElementCollector(doc);

    collector.WherePasses(orFilter);

    IList<Element> elementList = collector.ToElements();

}

It is also possible to encapsulate a list of categories with an ElementMulticategoryFilter (instead of a LogicalOrFilter joining multiple category filters).  The results should be the same but slightly less code to write.

cool, more simple!
