Hi all, Im trying to make a graph to make a certain design option of a designoption set primary. I tried this by using the orchid nodes for getting the design option set and design option. then applying this into a python script. It got me an error, could anyone help?

This is the python script:

```auto
# Load the Python Standard and DesignScript Libraries
import sys
import clr
clr.AddReference('ProtoGeometry')

# Load the Revit API and RevitServices
clr.AddReference("RevitAPI")
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager

# Import the Revit API
import Autodesk
from Autodesk.Revit.DB import *

# The inputs to this node will be stored as a list in the IN variables.
dataEnteringNode = IN

# Place your code below this line

# Function to set the primary design option
def set_primary_design_option(option_set, option):
    try:
        option_set.SetPrimary(option)
        return True
    except:
        return False

# Get the active Revit document from the input
doc = IN[0]

# Get the DesignOptionSet and DesignOption IDs from the inputs
option_set_id = IN[1]
option_id = IN[2]

# Find the DesignOptionSet and DesignOption by their IDs
option_sets = FilteredElementCollector(doc).OfClass(DesignOptionSet).ToElements()
option_set = [x for x in option_sets if x.Id == option_set_id][0]

options = option_set.GetDesignOptions()
option = [x for x in options if x.Id == option_id][0]

# Set the primary design option
result = set_primary_design_option(option_set, option.Id)

# Assign your output to the OUT variable.
OUT = result

```

My guess is that the orchid data isn’t valid in the Revit context, but I can’t confirm as I don’t have the [Orchid Package](https://github.com/erfajo/OrchidForDynamo) installed, best to ask on the linked GitHub.

Try using some custom packages to collect the current document instead of the OOTB node.

Or hard code the IN[0] input to the current doc (there are examples on the forums)

some packages containing these from memory.  
-Archilab  
-Crumple

Or even better search the [orchid package](https://github.com/erfajo/OrchidForDynamo) as this is likely the compatable method.

Hi Guys,

Recieved also an answer from Erfajo. ( [make a design option primary · Issue #213 · erfajo/OrchidForDynamo (github.com)](https://github.com/erfajo/OrchidForDynamo/issues/213))

Looks like there is no method to set a design option to primary yet.
