[Bug] InvalidObjectException when dimension references linked model elements

[jabergmp]

Affected node

Dimension.ReferencedElements

Problem description

Getting the following error when using the node on dimensions in the host model that reference linked model elements:

InvalidObjectException : Reference contained element ids not found in this document.
   at Autodesk.Revit.DB.Reference.ConvertToStableRepresentation(Document document)

Cause:
In GetDimensionReferences, when a reference points to a linked element, ConvertToStableRepresentation is being passed the linked document instead of the host document:
``
srefs.append(r.ConvertToStableRepresentation(item.Document.GetElement(r.ElementId).GetLinkDocument()))

A Reference object from a host dimension belongs to the host document context. Passing the link document causes the element ID mismatch and throws the exception.

Expected behaviour (optional)

No response

Clockwork version

3.3.0

Revit version

2026

A propsed fix is a one line change in GetDimensionReferences. When a reference points to a linked element, pass item.Document (host document) instead of the linked document to ConvertToStableRepresentation:

# Before
srefs.append(r.ConvertToStableRepresentation(item.Document.GetElement(r.ElementId).GetLinkDocument()))

# After
srefs.append(r.ConvertToStableRepresentation(item.Document))

This also works when the node is used on dimensions in a linked model, since item.Document always returns the document that owns the dimension regardless of context.

@jabergmp Nice catch!
