C# 2019 inquiring about "Parameter Exists" of ParameterFilterRuleFactory.

[klkl12234]

Hello, I am inquiring about "Parameter Exists" of ParameterFilterRuleFactory.

All filters applicable within "public class ParameterFilterRuleFactory" have been found.

FilterRule filterRule = ParameterFilterRuleFactory.CreateEqualsRule(paramId, f.ParameterValue, true);

FilterRule filterRule = ParameterFilterRuleFactory.CreateNotEqualsRule(paramId, f.ParameterValue, true);

FilterRule filterRule = ParameterFilterRuleFactory.CreateGreaterRule(paramId, f.ParameterValue, true);

...

"Parameter exists", Except for one thing.

Is there a way?

Thank you for your time.

Hi @klkl12234,

I am unable to clearly get your question and would request for more information.

Press the vv.

I want to add data as add-in in the "Filters" tab of "visibility/graphics override for 3D View : Navisworks Out View"

Edit/New..

Press the "Edit/New.." button to add 

"equals",

"does not equals",

 "is greater than"

"is greater than or equal to",

"is less than", 

"is less than or equal to",

etc...

from Filter Rules

The sources for this are as follows.

ParameterFilterRuleFactory.CreateEqualsRule(paramId, f.ParameterValue, true);

ParameterFilterRuleFactory.CreateNotEqualsRule(paramId, f.ParameterValue, true);

ParameterFilterRuleFactory.CreateGreaterRule(paramId, f.ParameterValue, true);

etc...

It's all there, but there's no "parameter exists".

@klkl12234,

I now get your question.

Unfortunately, the filter rule you are looking for is not supported yet in Revit based on the documentation given and also on the Revit UI Filters

Well, it won't hurt to submit this as a wish to the Revit Idea Station.

Whenever you require new or enhanced Revit product or Revit API functionality, the Revit Idea Station is the place to go.

Please search there for a corresponding wish list entry for the suggested functionality and add your comments to it, or create a new one, if none already exists:
