Hi,

After creating viewsheet i would to set parameter of drawn by and checked by with python script but i can’t find a good code.

Are you sure that’s the right method? String parameters just use Set(string). I believe that method is specifically for parameter values represented by string indicators.

Hi, as Nick mentioned, you should use the Set method.

Here’s a basic “Set parameters” script as example :

import clr

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

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import List

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

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

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

#Preparing input from dynamo to revit
element = UnwrapElement(IN[0])
param = IN[1]
values = IN[2]

done=[]
notDone=[]
#Do some action in a Transaction
for e,vList in zip(element,values):
	flag = False
	for p,v in zip(param,vList):
		TransactionManager.Instance.EnsureInTransaction(doc)
		elem_param = e.LookupParameter(p)
		if v == None or v == "":
			flag = True
		else:
			if not elem_param.IsReadOnly:
				elem_param.Set(v)
			else:
				flag = True
		TransactionManager.Instance.TransactionTaskDone()
	if flag:
		notDone.append(e)
	else:
		done.append(e)


OUT = done,notDone

Thanks

It works, I just discovered drawn by and checked by for viewsheet don’t need the buitInParameter to set value and the LookupParameter method is enought.
