I can add filters to a schedule, but is there a way to remove them? I see ClearAllFilters, but I want to remove a specific filter and leave others untouched. Am I missing something? ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/e/6e47aa56abd6bd2b6da5b36c48400d733fcf8380.png) ---

I’m pretty sure the only way would be to clear filters then re-add all but the intended ones. If you try to remove a filter in Revit naturally, you’ll notice it wipes out all filters below it, so pretty sure Dynamo would suffer from this if it supported removal. ---

Would this node suit your requirements? ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/e/2ef441c63809f2158415b75b6ebbf981cbc380f8.png) ---

I think it’s be doable via the API. There is a ‘remove filter’ method that takes the Element Id of the Filter element. There is also a GetOrderedFilters method to get a list of the filters in the order provided. Only question is if the filters provided differ between schedules and views as these are inherited methods. You might have to enable/disable the filters as you go, or force a regen though. Worth poking around of there is desire and someone has time. ---

Interesting… maybe they built it in as a helper behind the scenes to avoid the filter collapse. I’ll try to get a look into this shortly, as I feel like I didn’t get this to work another time I was trying to define filters in schedules. Maybe I can prove past me wrong. ---

I can confirm that it works 🙂 It is possible to remove one filter without effecting the others. Notice that these method for schedules does not take an element id, it works by index. It´s the method for views that takes an id. > **[RemoveFilter Method](https://www.revitapidocs.com/2023/57b69056-4175-3de4-511f-c1a1af280300.htm)** > > Online Documentation for Autodesk's Revit API: 2015, 2016, 2017, 2017.1, 2018 ```auto import clr clr.AddReference('RevitAPI') clr.AddReference('RevitServices') from Autodesk.Revit.DB import ViewSchedule from RevitServices.Persistence import DocumentManager from RevitServices.Transactions import TransactionManager doc = DocumentManager.Instance.CurrentDBDocument schedule = UnwrapElement(IN[0]) TransactionManager.Instance.EnsureInTransaction(doc) # remove filter by index schedule.Definition.RemoveFilter(0) TransactionManager.Instance.TransactionTaskDone() ``` @SURFACEFUSION , if you are not already familiar with that procedure, you will need a python script node and copy/paste the code! ---

This worked beautifully! I swapped out the “0” in the schedule.Definition.RemoveFilter for an “IN[1]” and I was able to input both the scheduleView and the index of the filter to remove. Thanks for all your help! ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/a/4a277db47591402f6dd5ded3b27b565be7481356.png)
