Question for Matching AnalyticalMember and FamilyInstance

[powerstrong]

I want to know some AnalyticalMember's properties. (for example, YZ_JUSTIFICATION)

I found that these properties are in FamilyInstance's parameters, by using RevitLookUp

Thank you Naveen and Jeremy 🙂

I can get list of AnalyticalMember by this :

AnalyticalModels = new FilteredElementCollector(RvtDoc).OfClass(typeof(AnalyticalElement)).ToElements();

And list of FamilyInstance by this :

var elements = new FilteredElementCollector(revitDoc)
 .OfClass(typeof(FamilyInstance))
 .WhereElementIsNotElementType()
 .Cast<FamilyInstance>()
 .ToList();

Now I want to get FamilyInstance from AnalyticalMember(AnalyticalElement).

I spent several hours to find relation with two data, but don't know.

Can anyone help me?

In 2023 if the element has been given an association via:
AnalyticalToPhysicalAssociationManager.AddAssociation

Then it can be found via:
AnalyticalToPhysicalAssociationManager.GetAssociatedElementId

I believe this method works both ways i.e. on both the analytical or the physical as the parameter.
