Autodesk.Revit.DB.UnitType.UT_Length

1

Hi!

Just a noob question :slight_smile:
I’m in trouble with those lines of code from a script written by learndynamo.com


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

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 :slight_smile:
I have another error, at line 34… I probably missed something:

	output.append(tempList)
#Assign your output to the OUT variable.
OUT[0] = output
OUT[1] = nameUnit
OUT [2] = UIunit.TypeId

try to replace

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

by

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

and

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

by

OUT = output, nameUnit, UIunit.TypeId
