Hey, I've tried your python code for my file but there were the following error>>> import arcpy
... from arcpy import env
... env.overwriteOutput = 1
...
... shp = r"S:\Public\Projekte\2011\11420\WVA Hochneukirchen\wasser.mdb\LK\WaEinbauten"
...
... with arcpy.da.SearchCursor(shp, ["GelaendeH"]) as cursor:
... for row in cursor:
... vertexElevation = row[0]
... arcpy.MakeFeatureLayer_management(shp, "pts_lyr", "Elevation = " + str(vertexElevation))
... arcpy.Adjust3DZ_management("pts_lyr", "NO_REVERSE", vertexElevation)
...
Runtime error Traceback (most recent call last): File "<string>", line 11, in <module> File "c:\program files (x86)\arcgis\desktop10.2\arcpy\arcpy\management.py", line 2101, in Adjust3DZ raise e ExecuteError: ERROR 000204: Fehler beim Erstellen des Eingabe-Feature-Cursors Fehler beim Ausführen von (Adjust3DZ).
>>>
Which means that the Input-Feature-Cursor could not be created, and the Adjust3DZ could not be run (I'm running the german version of ArcGIS)I've updated the path to my feature-class (wasser.mdb\LK\WaEinbauten) as well the elevation field (GelaendeH).
