Filter all model elements except symbol elements

[rita.aguiar]

How can I filter all model elements but not also the symbol elements?

I am creating a plugin using the Lab4_2_ExportParametersToExcel from the Revit API .NET Labs.

In Lab4_2_ExportParametersToExcel we are iterating "over all elements, both symbols and model elements, and then in the dictionary." (see attached .png)

How can I get all model elements but not the symbol elements?

The reason why I'm asking this is because when I run this plugin on a project with just a few columns and walls to make a small test, I get an endless list of elements (on an excel file) that I have no idea of where they came from and what they are, so I guess they might be symbol elements. (see excel file)

Any help would be appretiated

  [Transaction(TransactionMode.ReadOnly)]
  public class Lab4_2_ExportParametersToExcel : IExternalCommand
  {
    public Result Execute(ExternalCommandData commandData,
        ref string message, ElementSet elements )
    {
      UIApplication app = commandData.Application;
      Document doc = app.ActiveUIDocument.Document;

      // Extract and group the data from Revit in a dictionary,
      //where the key is the category name and the value is a list of elements.

      Stopwatch sw = Stopwatch.StartNew();

      Dictionary<string, List<Element>> sortedElements
        = new Dictionary<string, List<Element>>();

            // Iterate over all elements, both symbols and 
            // model elements, and then in the dictionary.

        ElementFilter f = new LogicalOrFilter(
        new ElementIsElementTypeFilter( false ),
        new ElementIsElementTypeFilter( true ) );

      FilteredElementCollector collector
        = new FilteredElementCollector( doc )
          .WherePasses( f );

The sample you are using is retrieving absolutely all Revit database elements.

It uses a union of two Booleans, one set to true, one to false.

This is not what you are after at all.

I suggest that you read a little bit more about the basics of filtered element collectors and implement your own filter that really does want you need and retrieves the elements you are interested in:

Hi,

This might be useful to you as an example how to filter all model elements.

If you are new to the Revit API i also recommend you to study how to use filtered element collectors, for your own need as Jeremy mentioned.

Hope this helps,

Cheers,
