Get assembly IDs and names

[Anonymous]

I am working on C# application and I would like to get a list of assemblies in an Revit existing file. I was able to find an example showing how to create an assembly and name it, but if assemblies are already created how would I get a list of those assembly IDs (to create views) and names?

This is part of what I have so far:

// Create assembly of selected components
transaction.Start("Create Assembly Instance");
AssemblyInstance assemblyInstance = AssemblyInstance.Create(doc, uidoc.Selection.GetElementIds(), categoryId);
transaction.Commit(); // need to commit the transaction to complete the creation of the assembly instance so it can be accessed in the code below
	             	
if (transaction.GetStatus() == TransactionStatus.Committed)
{
	// Set assembly name
	transaction.Start("Set Assembly Name");
	assemblyInstance.AssemblyTypeName = "My Assembly Name";
	transaction.Commit();
}

Any help would be greatly appreciated. Thank you

Thank you for the link, but I am trying to figure out how to get all of the AssemblyID and names in a project without selecting them. It seems that most tutorials tell me how to work with parts or assemblies that are selected, but this has to be possible, right?

Assemblies are Elements and have Ids. These two collectors will retrieve all Assembly Instances or Assembly Type from a project.

This will call the 'assemblyTypes' collector in the second code block.

	List<AssemblyType> assemblyTypes = Collectors.GetAssemblyTypesFromProject(_revitDoc);

Filtered Element Collectors - One to get Assembly Instances and anouther to get Assembly Types.

public static List<AssemblyInstance> GetAssemblyInstancesFromProject(Document revitDoc)
{
	var collector = new FilteredElementCollector(revitDoc).OfClass(typeof(AssemblyInstance));

	return collector.Cast<AssemblyInstance>().ToList();
}


public static List<AssemblyType> GetAssemblyTypesFromProject(Document revitDoc)
{
	var collector = new FilteredElementCollector(revitDoc).OfClass(typeof(AssemblyType));

	return collector.Cast<AssemblyType>().ToList();
}

For either list you would then iterate through the list appending each object with .Id or .Name

Interate over Assembly Types Example to Console

foreach(var assemblyType in assemblyTypes)
{
	Console.WriteLine(assemblyType.Id);
        Console.WriteLine(assemblyType.Name);
}

Chris, thank you for the help. I am sure you have answered my question, but I am having trouble getting this to work. Can you tell me how to define the "Collectors" variable? I am getting an error saying "Collectors does not exist in the current context".
