    Please find below code to export the first MAC Calculater Object as a csv file using Mechanical scripting.

    import os

nvh_addon = ExtAPI.ExtensionManager.GetExtensionByName("NVHToolkit")

#Define the path and file name for the export
dirpath = r"D:\del\mac_export"
filename = "test.csv"
file_path_to_csv = os.path.join(dirpath,filename)

nvh_addon.Attributes["exportdir"] = file_path_to_csv

mac_objects=ExtAPI.DataModel.GetUserObjects(nvh_addon)
nvh_module=nvh_addon.GetModule()
mac_data = nvh_module.MacData()
mac_data=nvh_module.ExportMAC(mac_objects[0])

    To further the excellent suggestion by Rohith, you could write this out to the user directory with the name of the design point in the csv file. This would allow you to post process the mode MAC with any external tool and allow to track modes.

    The MAC Calculator has to be built in the first DP and set to the .rst for that analyses. (The MAC calculator is from an extension and while scripted, not easily amenable to being accessed by script). So solve the first DP, set the MAC Calculator to a .rst and set the path, and then solve the rest of your DPs with the code below in an After Post Target Callback Python Code object.

    `
    def after_post(this, solution):# Do not edit this line
    """
    Called after post processing.
    Keyword Arguments :
    this -- the datamodel object instance of the python code object you are currently editing in the tree
    solution -- Solution
    """

    # To access properties created using the Property Provider, please use the following command.
# this.GetCustomPropertyByPath("your_property_group_name/your_property_name")

# To access scoping properties use the following to access geometry scoping and named selection respectively:
# this.GetCustomPropertyByPath("your_property_group_name/your_property_name/Geometry Selection")
# this.GetCustomPropertyByPath("your_property_group_name/your_property_name/Named Selection")

import wbjn
import os

dp=wbjn.ExecuteCommand(ExtAPI,"returnValue(Parameters.GetCurrentDesignPoint().DisplayText)")
UserFilesDirectory = wbjn.ExecuteCommand(ExtAPI, "returnValue(GetUserFilesDirectory())")


nvh_addon = ExtAPI.ExtensionManager.GetExtensionByName("NVHToolkit")
#Define the path and file name for the export
dirpath = UserFilesDirectory
filename = 'MAC_%s.csv'%dp.replace(' ','_')
file_path_to_csv = os.path.join(dirpath,filename)
nvh_addon.Attributes["exportdir"] = file_path_to_csv
mac_objects=ExtAPI.DataModel.GetUserObjects(nvh_addon)
nvh_module=nvh_addon.GetModule()
mac_data = nvh_module.MacData()
mac_data=nvh_module.ExportMAC(mac_objects[0])

pass

    `
