Automatically reassigning annotation style and dim scale

Hey all,

New to scripting so fingers crossed this is a simple fix. The gist of what I’m trying to do is automate a process for taking old architectural details imported from CAD and reassign their annotation style to a uniform one with a variable model space scale - that variable model space scale being determined by what the original annotation style is and assigned via a csv file. Generally, I’m able to get everything to work up until the last step - that being assigning the custom scale. Is this possible / am I missing something obvious? Thanks!

import rhinoscriptsyntax as rs
import csv
import Rhino
import System

def reassign_annotation_style():
    # Select the object
    obj = rs.GetObject("Select an annotation object", rs.filter.annotation)
    if not obj:
        return

    # Get the current annotation style
    current_style = rs.DimensionStyle(obj)

    # Prompt user to select the CSV file
    filter = "CSV Files (*.csv)|*.csv|All Files (*.*)|*.*||"
    csv_file = rs.OpenFileName("Select the annotation scales CSV file", filter)
    if not csv_file:
        print("No CSV file selected. Operation cancelled.")
        return

    # Read the CSV file for scale information
    scale_dict = {}
    try:
        with open(csv_file, 'r') as csvfile:
            reader = csv.DictReader(csvfile)
            for row in reader:
                scale_dict[row['OriginalStyle']] = float(row['ModelSpaceScale'])
    except Exception as e:
        print("Error reading CSV file: {}".format(str(e)))
        return

    # Set the new annotation style
    new_style = "Paperspace"
    rs.DimensionStyle(obj, new_style)

    # Apply the model space scale
    if current_style in scale_dict:
        scale = scale_dict[current_style]
        
        # Get the dimension style
        dim_style = rs.DimensionStyle(new_style)
        
        if dim_style:
            # Create a new dimension style with the updated scale
            new_style_name = "{}_{}_Scale".format(new_style, scale)
            new_dim_style = rs.CopyDimensionStyle(new_style, new_style_name)
            
            # Set the new scale
            rs.DimensionScale(new_dim_style, scale)
            
            # Apply the new style to the object
            rs.DimensionStyle(obj, new_style_name)
            
            print("Annotation style changed from '{}' to '{}' and scaled by {}".format(current_style, new_style_name, scale))
        else:
            print("Unable to find the '{}' dimension style.".format(new_style))
    else:
        print("Annotation style changed from '{}' to '{}', but no scale found in CSV".format(current_style, new_style))
