Hi!

Just a noob question 🙂  
I’m in trouble with those lines of code from a script written by [learndynamo.com](http://learndynamo.com)

```auto

getDocUnits = doc.GetUnits()
getDisplayUnits = getDocUnits.GetFormatOptions(Autodesk.Revit.DB.UnitType.UT_Length).DisplayUnits

```

Does anybody know how to solve this? I’m working on Revit 2023.

Thanks!

UnitType is no more. It was replaced with ForgeTypeId.  
Use GetSpecTypeId()

Hi @dgeorge  
here an example

```auto
import sys
import clr

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

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager

#Get Important vars
doc = DocumentManager.Instance.CurrentDBDocument

UIunit = doc.GetUnits().GetFormatOptions(SpecTypeId.Length).GetUnitTypeId()
nameUnit = LabelUtils.GetLabelForUnit(UIunit)

OUT = nameUnit, UIunit.TypeId

```

Thanks so much! The script just ran fine over those lines 🙂  
I have another error, at line 34… I probably missed something:

try to replace

`height = Autodesk.Revit.DB.UnitUtils.ConvertFromInternalUnits(height, getDisplayUnits )`

by

`height = Autodesk.Revit.DB.UnitUtils.ConvertFromInternalUnits(height, getDocUnits )`

and

```auto
OUT[0] = output
OUT[1] = nameUnit
OUT [2] = UIunit.TypeId

```

by

`OUT = output, nameUnit, UIunit.TypeId`
