Dear All, I am new to the forum and trying to set up Filter Rules using FilterRule.ByRuleType and ParameterFilterElement.ByRules. However, the list of the rules I created is using “AND” by default. How to change to “OR”? Please see the attached images. [Capture_2]

I am also looking for a way to do this. Anyone know a way?

Maybe take a look at: ParameterFilterElement.SetRules() → ParameterFilterElement.SetElementFilter() – The new function sets the ParameterFilterElement to contain an ElementFilter representing the combination of filter rules. I don’t think any packages have this yet, so you may need python? …

Hello @Ben_Osborne i have tried to follow your outline for 2020 and have run into one issues. I cant really work out how to set the rules, I have attached the script, but basically I try and create a rule that sets a typename- but it just doesnt want to work. Blockquoteimport clr clr.AddReferen…

an excellent detailed description, @Ben_Osborne . Thank you for taking the time for that. One quick question, why is “False” added to the end of each rule (below in bold, your code) The FilterStringRule constructor does not seem to have a boolean in its syntax. xFamName=FilterStringRule(pFamName,F…
