Changing an Element's Phase Created Parameter

[62BJW]

I'm attempting to change the Phase Created parameter of all elements to "Existing". Sounds as simple as either of the following but neither is working.

                element.get_Parameter(BuiltInParameter.PHASE_CREATED).Set(phaseCreated.Id);
                element.get_Parameter(BuiltInParameter.PHASE_CREATED).SetValueString("Existing");

I've looked at many threads including the ones below but nothing works.

Thanks for the help.

Dear Bernie,

Thank you for your query.

Have you tried setting an element's phase created parameter manually through the user interface and monitoring what effect that has on its parameters via the API, e.g., using RevitLookup?

What do you observe when doing that?

Best regards,

Jeremy

Hi @62BJW ,

To set the PhaseCreated parameter first filter for the "PhaseName" and try to set the phase to the element as mentioned in the code

 Element yourElement;
                FilteredElementCollector collector = new FilteredElementCollector(doc).OfClass(typeof(Phase));               
                var phases = from Phase phase in collector where phase.Name.Contains("Existing") select phase;
                ElementId phaseID = phases.First().Id;     
                
                //Set phaseId 
                yourElement.CreatedPhaseId = phaseID;

I hope this helps.

I can see that there is a parameter called CreatedPhaseId but its value is not consistent between files.

For example in one file the CreatedPhaseID value is <Phase  New Construction  118390> and in another it's value is <Phase  New Construction  109562>

Thanks for the reply Naveen. Not sure I completely understand the code you provided. Won't the FilteredElementCollector get elements that are set to "Existing"? I'm looking to get all "New Construction" and set it to "Existing". I can change it around but I'm not sure what element.CreatedPhaseId = phaseID; is attempting to do. If the collector is finding elements of a particular phase isn't phaseID set to the same phase and therefore not changing it?

Dear Bernie,

Thank you for your update.

I guess phases get created as you go along and as they are needed one by one, so therefore you will find they have different phase ids in different models.

That is why Naveen suggests you retrieve the desired phase from the current BIM collection of phases first, in one collector, determine its id, and use that to set the desired value on the BIM element parameters.

What part of this are you unclear about?

Best regards,

Jeremy

Thanks Jeremy,

I think I understand the collector but I’m unclear how to actually change the phase of the elements in my foreach loop.

Hi @62BJW ,

1)In your project, Filter for the phase named as "Existing".(as I suggested in my previous comments)

2)Get the "Existing" phase ID(It doesn't matter even if your PhaseId changes for every project because from the phase name you are getting the ID so your ID won't go wrong)

FilteredElementCollector collector = new FilteredElementCollector(doc).OfClass(typeof(Phase));
var phases = from Phase phase in collector where phase.Name.Contains("Existing") select phase;
ElementId existingPhaseID = phases.First().Id;

3)using FilteredElementCollector(let's say elementslist), collect all your elements in your project or use appropriate filters to collect particular elements present inside the project to change the Phasecreated property.

4)use foreach loop and iterate over each element and check if the element's phase is "existing phase", if not use the below code to change the Phasecreated property

foreach(Element e in elementsList)
                {
                    if (e.CreatedPhaseId != existingPhaseID)
                    {
                        e.CreatedPhaseId = existingPhaseID;
                    }
                }

where "elementslist" is the list of elements collected using the filteredelementcollector.

1)I'm not sure what element.CreatedPhaseId = phaseID???

ans:This is the way to change or set your phase name to "Existing" using the phaseId of existing phase.

I hope this helps and even if you have any doubts feel free to post your questions.

Thanks for the help Naveen.

"3)using FilteredElementCollector(let's say elementslist), collect all your elements in your project or use appropriate filters to collect particular elements present inside the project to change the Phasecreated property."

Are you saying change collector to elementlist? See attached image.

Hi @62BJW ,

Yes, what you are doing is correct but normally I collect the elements via filteredelementcollector and add it to a LIST and I always use List elements.

Lets say suppose you want ElementID instead of elements then you have to use IList<> or Icollection<> which will help you to save your elements in list as Elementids.

[jeremytammik]

You should always avoid converting from a filtered element collector to a List if you are not forced to do so for some reason:

• http://thebuildingcoder.typepad.com/blog/2012/09/findelement-and-collector-optimisation.html
• https://thebuildingcoder.typepad.com/blog/2018/11/efficient-elegant-code-and-automatic-dashboard.htm...

It is a total waste of memory and processing time.

It also forces the filtered element collector to retrieve all the elements in one go, which may be extremely undesirable in a large model.

Thanks Naveen and Jeremy for the replies. Sounds like I should not add element from the collector to a list in this case correct? If so I;m getting an error when I run the code. Please see attached image. Thanks.

After experimenting a bit and stepping through the code I found that the FilteredElementCollector is collecting the phase names in the model not elements with a particular phase ("Existing"). How do I tweak it to collect the elements with "Phase Created" set to "Existing"? Thanks.

            FilteredElementCollector elementslist = new FilteredElementCollector(doc).OfClass(typeof(Phase));
            var phases = from Phase phase in elementslist where phase.Name.Contains("Existing") select phase;
            ElementId existingPhaseID = phases.First().Id;

Try this;

https://thebuildingcoder.typepad.com/blog/2010/09/filter-for-view-and-phase.html

And then try removing the doc.ActiveView.Id from the following;

FilteredElementCollector collector 
      = new FilteredElementCollector( 
        doc, doc.ActiveView.Id );
