Display unit type not defined

Revit

Hi All. I know there is a similar topic to this one. Question is, what code do I replace DisplayUnitType with? I know it changed in the api but cant find the correct syntax. So with the below, what do I simply need to change it to the correct syntax?

def locToCutCrv(wall, wallNormal, lineEndExtend, locPos):
wallLn = wall.Location.Curve
#we’re using Design Script for the geometry move, so Metric units
wallCrv = wallLn.ToProtoType()
locPositionMM = UnitUtils.ConvertFromInternalUnits(locPos, DisplayUnitType.DUT_MILLIMETERS)

Hi @technitutors ,

Maybe this will help?

import Autodesk.Revit.DB as RDB
revit_version = int(doc.Application.VersionNumber)

# code omrekenen revit feet naar huidig ingestele document units
if revit_version >= 2022:
    ForgeLength = "autodesk.spec.aec:length-1.0.0"  # zie voor lijst ForgeTypeIds.xlsx in de map handleidingen
    ForgeTypeLength = RDB.ForgeTypeId(ForgeLength)
    getDocUnits = doc.GetUnits()
    getDisplayUnitsLength = getDocUnits.GetFormatOptions(ForgeTypeLength).GetUnitTypeId()
else:
    getDocUnits = doc.GetUnits()
    getDisplayUnits = getDocUnits.GetFormatOptions(RDB.UnitType.UT_Length).DisplayUnits

# Hieronder kun je de definitions gaan opzetten

#dynamo waarde omzetten naar revit units length     
def ToRevitUnitsLength(InVal):
    if revit_version >= 2022:
        return RDB.UnitUtils.ConvertToInternalUnits(InVal, getDisplayUnitsLength)
    else:
        return RDB.UnitUtils.ConvertToInternalUnits(InVal, getDisplayUnits)
        
#revit waarde omzetten naar dynamo units length   
def ToDynamoUnitsLength(InVal):
    if revit_version >= 2022:
        return RDB.UnitUtils.ConvertFromInternalUnits(InVal, getDisplayUnitsLength)
    else:
        return RDB.UnitUtils.ConvertFromInternalUnits(InVal, getDisplayUnits)
        
#dynamo waarde omzetten naar revit units length van mm   
def ToRevitUnitsLengthFromMM(InVal):
	if revit_version >= 2022:
		return RDB.UnitUtils.Convert(InVal, RDB.UnitTypeId.Millimeters, RDB.UnitTypeId.Feet)
	else:
		return RDB.UnitUtils.Convert(InVal, RDB.DisplayUnitType.DUT_MILLIMETERS, RDB.DisplayUnitType.DUT_DECIMAL_FEET)

so this goes before the script I wrote?

What revit version you are using ?

2023

In Revit 2023, you should update API
Older Revit 2023 :

locPositionMM = UnitUtils.ConvertFromInternalUnits(locPos, DisplayUnitType.DUT_MILLIMETERS)

Revit 2023 or higher :

locPositionMM  = UnitUtils.ConvertFromInternalUnits(locPos, UnitTypeId.Millimeters)

@technitutors
You can use this def.

It is the same what @chuongmep suggest, this definition can be used in every revit version.
