Location of a point with respect to survey point?

1

I am trying to find the location of an element with respect to survey point but instead I am getting it w.r.t to project basepoint. Can someone help me to achieve it?

Project basepoint is rotated w.r.t true north also.

Thanks. Let me have a look. It seems it finds distance between the 2 points.

Here is an example with Python

import sys
import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument

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

toList = lambda x : x if hasattr(x, '__iter__') else [x]

lst_DSPt = toList(IN[0])
out = []

for pt in lst_DSPt:
    pt = pt.ToXyz()
    #translate point from  Internal to Shared coordinates
    translatedpointB = doc.ActiveProjectLocation.GetTotalTransform().Inverse.OfPoint(pt)
    out.append([translatedpointB.ToPoint().X, translatedpointB.ToPoint().Y, translatedpointB.ToPoint().Z])
OUT = out
