By Xiaodong Liang

SelectionSets is a collection. It can contain Folder and common SelectionSet. A Folder is a GroupItem that can include common SelectionSet as well. The code below is a demo on how to create a common SelectionSet and a Folder, and how to move the common set to the folder.

public void testSelectionSet()

{

    Document oDoc =

       Autodesk.Navisworks.Api.Application.ActiveDocument;

 

    // get the selection sets

    DocumentSelectionSets oSets =

            oDoc.SelectionSets;

 

     // create a search and conditions

    Search s = new Search();

 

    SearchCondition sc =

        SearchCondition.HasPropertyByDisplayName("Element",

                                                "Category");

    s.SearchConditions.Add(

sc.EqualValue(VariantData.FromDisplayString("Walls")));

 

    //set the selection to everything

    s.Selection.SelectAll();

    s.Locations =

        SearchLocations.DescendantsAndSelf;

 

    SavedItem newItem = new SelectionSet(s);

    newItem.DisplayName = "MySearchSet";

    //add to the end

    oSets.AddCopy(newItem);

 

    //folder

    FolderItem oFolder = new FolderItem();

    oFolder.DisplayName = "MyFolder";

    // add to the end

    oSets.AddCopy(oFolder);

 

    try

    {               

        //index of the common selection set        

        int indexOfSaveditem = oSets.Value.Count - 2;      

            

        // move the  selection set  to the folder         

        oSets.Move(oSets.RootItem, indexOfSaveditem,

            (GroupItem)oSets.Value.Last<SavedItem>(), 0);

    }

    catch (Exception ex)

    {

        MessageBox.Show(ex.ToString());

    }

}
