Extracting a named reference plane from FamilyInstance

[harilalmn]

Dear All,
I have been struggling to extract a particular reference plane named "Aligned". I need to create a plane that is at exact orientation of the reference plane inside the FamilyInstance. I used the GetReferenceByName() method, as follows;

FamilyInstance familyInstance = doc.GetElement
(
uiDoc.Selection.PickObject(
Autodesk.Revit.UI.Selection.ObjectType.Element,
new FamilyInstanceFilter(),
"Select a family instance")
) as FamilyInstance;

Reference alignReference = familyInstance.GetReferenceByName("Aligned");

I saw several posts with solutions here, for creating dimensions using the GetReferenceByName(), but could not find one with solution to extract the plane.

How to do this?

The plane exists only in the family definition, so I doubt that you will be able to access it without opening your RFA, e.g., using EditFamily.

Is the reference plane you are looking for set to 'Not a Reference' in family? Otherwise according to RevitAPI.chm (as I understand it) it should be able to find it.

I am able to find the reference...

Here is the scenario. I have several families which when placed in project, are to be aligned to some walls. Each family has a reference plane named "Aligned". When placing, this reference plane has to align with the given wall, as if we do manual align in revit using "AL" shortcut.

Above shown is what I try to achieve...

I have several families and each family has different orientation for this reference plane.
