1. 首先，我们需要用BIM 360的API创建一个新的项目。

2. 然后，我们需要复制一个已有项目中的文件夹，作为新项目的模板。

3. 然后，我们需要在新项目中创建一个空的文件夹，作为复制后的文件夹的目标。

4. 接下来，我们需要使用BIM 360的API将复制的文件夹复制到新项目的目标文件夹中。

具体的代码示例如下：

import requests
import json

# Step 1: Creating a new project
url = 'https://developer.api.autodesk.com/hq/v1/accounts/:account_id/projects'
headers = {'Authorization': 'Bearer ' + access_token, 'Content-Type': 'application/json'}
payload = {
    "name": "New Project",
    "projectType": "bim360",
    "services": {
        "documentManagement": {
            "serviceType": "BIM 360 Docs"
        }
    },
    "industryRoles": {
        "projectAdmin": [
            "USER-A"
        ]
    },
    "permissionTemplateKey": "project_administration"
}
response = requests.post(url, headers=headers, data=json.dumps(payload))
response_json = json.loads(response.text)
project_id = response_json['data']['id']

# Step 2: Duplicating template folder
url = 'https://developer.api.autodesk.com/data/v1/projects/:project_id/folders/:folder_id/copy'
headers = {'Authorization': 'Bearer ' + access_token, 'Content-Type': 'application/json'}
payload = {
    "jsonapi": {
        "version": "1.0"
    },
    "data": {
        "type": "folders",
        "attributes": {
            "name": "Template Folder - Copy"
        },
        "relationships": {
            "parent": {
                "data": {
                    "type": "folders",
                    "id": "root"
                }
            },
            "source": {
                "data": {
                    "type": "folders",
                    "id": "
