So I’m struggling to get my filter rule by rule type working… I want to filter by Level, so I believe I need to feed both the Level Parameter (ie. a parameter) from the floor and the Level Parameter value (ie. a string). My attempts at retrieving the parameter by name don’t seem to be working (I c…

Gotcha! [image] The first BIP LEVEL_PARAM didn’t work, it needs the 2nd… I’ll have to run some kind of check… pId = ElementId(BuiltInParameter.SCHEDULE_LEVEL_PARAM) sRule = ParameterFilterRuleFactory.CreateEqualsRule(pId, level.Id) fRule = ElementParameterFilter(sRule) #Do some action in a Tra…

I don’t think GetElement works for parameter elements. You could probably use something like GetParameters or LookupParameter instead.

Thanks Nick, I’m wondering if I’m looking at the wrong problem… I think the filter rule should work if i put the level in, but it only returns a filter if i put in a string (the level name)… I’m seeing if i can doctor this code… [image] Can't add filter rules with FilterRule.ByRul…

Correct. The input is actually a string here, which is backwards from how the Level parameter would normally work. It’s working on my end. [image]

I find it makes a rule, but when i go look at that in Revit, it’s empty? [Hopes it’s just me] [image]

You’re right. Blank for me as well. I’m guessing it’s because the FilterRule node expects a string but the value for Level is an element. I’m guessing this will have to be fixed in an update.

Thanks! I don’t think i have that node! I’ll go update my package now… I have Archilab 2019.2.11 are you on a more recent version?

No I’m on an older version. It doesn’t seem to work either. The rule gets created but the filter doesn’t.

Hum… It’s not there, I’m messing around with the Python but getting this message, probably because I’m using a string equals filter… [image] But I can’t see a create method for a filter rule that isn’t a string? https://www.revitapidocs.com/2020/c8c02bc8-5318-812c-e0f2-bc5dd5d2ad64.htm import …

maybe you can should your final desired output of the filter rules and i will try and help you to code with it? Note that in R18 and above, it uses different approach as compared to R17 and below. And the sample code you got is for R18 and above

And also, i dont think you need to feed in an element to retrieve the parameter Id, you can either use parametermap for project or sharedparameter element and filter by name to retrieve its Id

Is it possible to feed FilterRule.ByRuleType node with type parameters?
