Handling ViewSheetSet in Revit: Alternatives to OrderedViewList
In the realm of Revit API development, the introduction of the OrderedViewList property in the 2023 version of Revit was a significant enhancement for managing view sheet sets. However, to developers who are still using previous Revit versions, this property is glaringly absent, creating a hurdle for those automating specific tasks like filling out issued date columns in sheet lists. If you've encountered this situation and are on a quest for a suitable workaround, you're not alone. This guide aims to shed light on effective alternatives for managing ViewSheetSet in earlier Revit versions.
The Challenge at Hand
As a Revit API developer, you may have built an add-in that necessitates fetching all view sheet sets, adding them to a user interface, and structuring a dictionary for referencing purposes. Your initial implementation may have relied on the OrderedViewList property to tally and arrange drawing sheets easily. But what happens if you're interfacing with an Revit version that doesn't support this? You might find yourself brainstorming alternatives to achieve your goal of efficiently managing sheet sets.
Key Points of Concern:
Absence of OrderedViewList: This essential property isn't available in versions prior to 2023, leading to potential roadblocks in your implementation.
Sloppiness of Alternatives: Certain proposed approaches, like collecting views with non-null set values, seem time-consuming or untidy.
Desire for Simplicity: Ideally, you'd want a cleaner, more effective method for managing ViewSheetSet without losing your way in complex code logic.
Crafting a Solution
After some reflection and a fresh perspective, a more pleasant path forward becomes apparent. The key is to switch perspectives on how to access views within the ViewSheetSet. Instead of relying on the non-existent OrderedViewList, we can utilize the Views property while implementing a simple enumeration approach.
The New Approach: Leveraging Views Property
Here's how to adapt your existing code to ensure it works seamlessly across both newer and older versions of Revit.
Collecting Elements: Continue fetching all ViewSheetSet objects as before using FilteredElementCollector.
Iterating Through Sets: During the iteration of each ViewSheetSet, access the Views property to retrieve the associated views and create a new list for your filtering needs.
Filtering and Counting: You can then filter the new view list for elements of type ViewType.DrawingSheet, allowing you to dynamically count the sheets associated with each view sheet set.
Example Code Implementation:

In this refined code snippet, we effectively create a list of views from the Views property, making it quite straightforward to filter and count relevant sheets. What was once a cumbersome task has been simplified effectively.
Conclusion: Finding Clarity in Complexity
When working with the Revit API, adjusting to the resources available in your particular version can be quite challenging. However, by pivoting your method of accessing view sheets and leveraging existing properties judiciously, you can streamline your tasks and improve your add-in's efficiency significantly.
Remember, each challenge presents an opportunity for innovation. Don't hesitate to step back, analyze your situation, and approach the problem from a fresh angle, just as we did here with the Views property and a thoughtful enumeration strategy.
