Geometry from linked file, by shared coordinates, appears on the wrong place in Dynamo

Sorry for the delay, here’s the python code which takes a document (linked instance) as input and outputs the linked document’s total transform as a point.

#Written by Scott Lebow
import clr

clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.GeometryConversion)

linkInst = UnwrapElement(IN[0])

totalTransform = linkInst.GetTotalTransform()
origin = XYZ(0, 0, 0)
offsetPoint = totalTransform.OfPoint(origin)

#Assign your output to the OUT variable.
OUT = offsetPoint.ToPoint()

From here you can create a Vector using this point (linkOffsetPoint).
DesignScript:
linkOffsetVector = Vector.ByTwoPoints(Point.ByCoordinates(0, 0, 0), linkOffsetPoint);

Or with nodes:

Then you can translate your point along this vector using Designscript:

newLocations = Point.Add(linkedElements.Location, linkOffsetVector);

Or the Point.Add node:
