Depreciated ParameterFilterElement.SetRules - Small Documentation Error

[grahamcook]

Hi

Was just migrating some code from 2018 to 2020 and was replacing the depreciated ParameterFilterElement.SetRules method with ParameterFilterElement.SetElementFilter.  I looked at the documentation for some guidance:

https://www.revitapidocs.com/2019/b231dc85-516a-5e75-c634-c6cd81b43fc5.htm

The c# example refers to a method (CreateElementFilterFromFilterRules) that does not exist.  The line:

ElementFilter elemFilter = CreateElementFilterFromFilterRules(filterRules);

needs replacing with:

List<ElementFilter> elemFilters = new List<ElementFilter>();
foreach (FilterRule filterRule in filterRules)
{
    ElementParameterFilter elemParamFilter = new ElementParameterFilter(filterRule);
    elemFilters.Add(elemParamFilter);
}

LogicalAndFilter elemFilter = new LogicalAndFilter(elemFilters);

Thanks.

Dear Graham,

Thank you for your report and sharing the workaround.

Sorry to hear about this.

I logged the issue REVIT-149071 [API documentation error: ParameterFilterElement Class: CreateElementFilterFromFilterRules] with our development team for this on your behalf as it requires further exploration and possibly a modification to our software. Please make a note of this number for future reference.

You are welcome to request an update on the status of this issue or to provide additional information on it at any time quoting this change request number.

By the way, 'deprecated' has no 'i' in it  🙂

Here are another couple of samples of using filter rules:

Hey. This code still doesn’t work for me.

LogicalAndFilter elemFilter = new LogicalAndFilter(elemFilters);

How to further apply this LogicalAndFilter in view?

Here are samples showing how to use LogicalAndFilter:

I thought this code should add a filter to the view. For 2020 version
LogicalAndFilter is about it?
