How to get all assembly codes and descriptions

[Anonymous]

Hi! I need to retrieve all assembly codes and descriptions of my model.

As far as I know, each Assembly Code/Description is a ClassificationEntry and those are stored in a KeyBasedTreeEntriesLoadContent object.

I was trying this, but I think I need to initialize the KeyBasedTreeEntriesLoadContent object. The problem is that there's no constructor...

UIApplication uiapp = commandData.Application;
Document doc = uiapp.ActiveUIDocument.Document;

KeyBasedTreeEntriesLoadContent content = null;
ClassificationEntries.LoadClassificationEntriesFromFile(doc.PathName, content);

foreach (ClassificationEntry elem in content.GetEntries())
{
//Does something with each elem
}

Thank you in advance.

I found a solution for my problem. It turns out those values are included as parameters of element types.

You can iterate through each element type and do:

string assemblyCode = elementType.get_Parameter(BuiltInParameter.UNIFORMAT_CODE).AsString();

string assemblyDescription = elementType.get_Parameter(BuiltInParameter.UNIFORMAT_DESCRIPTION).AsString();

I still don't know if there's better way to get all of them directly, without iterating though all the elements, but this works for my problem as I already need to iterate through them.

ClassificationEntries.LoadClassificationEntriesFromFile() provides you to load the contents from classification text file into the provided KeyBasedTreeEntriesLoadContent (as revitapidocs.com says)

To get all assembly codes and descriptions use this:

        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            UIApplication uiApp = commandData.Application;
            Document doc = uiApp.ActiveUIDocument.Document;
            AssemblyCodeTable assemblyCodeTable = AssemblyCodeTable.GetAssemblyCodeTable(doc);
            ClassificationEntries classificationEntries = assemblyCodeTable.GetKeyBasedTreeEntries() as ClassificationEntries;
            foreach (ClassificationEntry entry in classificationEntries)
            {
                string assemblyKey = entry.Key;
                string assemblyDescription = entry.Description;
                //do your stuff
            }

            return Result.Succeeded;
        }

This is a nice way to get all the content (Key and Description) from the AssemblyCodeTable.

How can I find the filename of the loaded Assembly Code File? (so the *.txt file)

I want to be able to check if the correct file is loaded in the project.

Thanks in Advance,

Hello, if you need to find the name of the downloaded assembler code file, you can use this code:

public static string GetAssemblyCodeTableFilePath(Document doc)
{
ExternalResourceType refType = new ExternalResourceType(new Guid ("cf823dbb-21d2-42e0-a39c-1cb523a8cec2"));
ExternalResourceReference externalResource = AssemblyCodeTable.GetAssemblyCodeTable(doc).GetExternalResourceReference(refType);
if (externalResource != null)
{
return externalResource.InSessionPath;
}
else
{
return null;
}
}
