Hi,

you can use Selection.SetReferences()

there is an example here

cool! thanks c.poupin, i managed to get linked element but how to convert that linked element to reference so it can be used in Selection.SetReferences()

tried below Python code but not working:

linkElems = UnwrapElement(IN[0])
linkInstance = UnwrapElement(IN[1])
linkReferences = List[Reference]([Reference(linkElem).CreateLinkReference(linkInstance) for linkElem in linkElems])
uidoc.Selection.SetReferences(linkReferences)

try this version

no luck, i assume it’s version issue, i’m using Revit 2024, which version are you using? by the way, linked elements highlighted because of selecting which is not desired, or after running script which is desired.

Tested on Revit 2024 and 2026

Can you share a simple RVT file with which the process fails (as a linked file) ?

tested w/ new RVTs, works great! i need to take another look at project RVT and script, very appreciated for your help c.poupin!

edit: found a bug in my script, works great now w/ minor change, thanks again for your help c.poupin.

is it doable to have both host elements and linked elements highlighted, currently i have to do it separated, kind of combining below 2 lines together

for host elements → uidoc.Selection.SetElementIds()

for linked elements → uidoc.Selection.SetReferences()

edit: did a test, cannot use both, means host elements also need to be converted to references and only use uidoc.Selection.SetReferences() i believe

edit: works OK now
