Hi,
It looks to me the collection of Models in .NET API is read-only. The following is a workaround. It deletes all files and append them again with the new order. I know you would hate such way, but this may be the way we have to go currently.
using ComApi = Autodesk.Navisworks.Api.Interop.ComApi;
using ComBridge = Autodesk.Navisworks.Api.ComApi.ComApiBridge ;
namespace MyDemoPlugin
{
[PluginAttribute("MyDemoPlugin", "ADSK", DisplayName = "demo")]
public class Class1:AddInPlugin
{
public override int Execute(params string[] parameters)
{
Document oDoc = Autodesk.Navisworks.Api.Application.ActiveDocument;
try
{
//sorting the names of the models
IEnumerable<Model> oNewSortedModels = oDoc.Models.OrderBy(per => per.RootItem.DisplayName);
List<string> fileArray = new List<string>();
foreach (Model oEachModel in oNewSortedModels)
{
fileArray.Add(oEachModel.FileName );
}
//delete all files.
foreach (Model oEachModel in oDoc.Models)
{
// State.DeleteSelectedFiles failed to delete
// all files at one time.
// so have to delete them one by one.
ModelItemCollection oMC = new ModelItemCollection();
oMC.Add(oEachModel.RootItem);
oDoc.CurrentSelection.CopyFrom(oMC);
ComBridge.State.DeleteSelectedFiles();
}
//append them again with the new order
oDoc.AppendFiles(fileArray);
}
catch(Exception ex)
{
}
return 0;
}
}
}
