首先，需要在Autodesk Forge上注册一个账户获取access token来访问API。然后，使用以下代码示例创建一个新的设计自动化活动并将其分配到欧洲服务器：

import requests
import json

# Replace YOUR_ACCESS_TOKEN with your actual access token
headers = {'Authorization': 'Bearer YOUR_ACCESS_TOKEN', 'Content-Type': 'application/json'}

# The design automation activity payload
data = {
    "id": "MyActivity",
    "commandLine": "$(engine.path)\\InventorCoreConsole.exe /i $(args[inputFile].path) /al $(appbundles[MyApp].path)",
    "parameters": {
        "inputFile": {
            "verb": "get",
            "description": "Input Inventor file",
            "required": true,
            "localName": "$(args[inputFile].path)"
        }
    },
    "engine": "Autodesk.Inventor+23",
    "appbundles": ["MyApp+0.1"],
    "settings": {
        "script": {
            "value": "// Some script"
        }
    },
    "version": 1,
    "description": "My Activity"
}

# Make a POST request to create the activity and assign it to the European server
response = requests.post('https://developer.api.autodesk.com/da/us-east/v3/activities',
                         headers=headers, json=data)

此代码中，我们假设您在Autodesk Forge上已经创建了一个名为“MyApp”的应用程序包和复制了一个名为“InventorCoreConsole.exe”的程序文件到该应用程序包。

最后，我们使用以下代码示例提交一个新的设计自动化作业，并指定该作业在欧洲服务器上运行：

# The design automation job payload
data = {
    "activityId": "MyActivity",
    "arguments": {
        "inputFile": {
            "url": "",
            "localName": ""
        },
        "outputFile": {
            "verb": "put",
            "description": "Output Inventor file",
            "localName": "
