Select Linked Element without Selecting Link

Packages
1

Hi,

Problem is we have 32 linked file in our model(mechanical, architectural, structural, electrical links at the same model.) I would like to write linked room number to my mechanical equipment but first I have to fight to select correct link from linked 32 file :slight_smile:

So i modify the “Springs.SelectLinkedElement” node as below. Now i just select link at the begining.
It works fine at DYNAMO but sadly not in DYNAMO PLAYER.
I don’t know why but “Links” node is not working at dynamo player.
I’m always getting “Inputs needed” error.

Constant%20Link
Constant Link.PNG920Ă—644 117 KB

So i’m think that is there any way to select linked element without selecting linkinstance?

-Feeding node with all link instance at document
-Select linked element with “Selection.ObjectType.LinkedElement”
-Find elements linked file.

Any help on this would be great.
