使用API接口上传和管理项目文件，以避免Autodesk Construction Cloud的限制。以下是示例代码：

from AutodeskConstructionCloud.ApiClient import ApiClient
from AutodeskConstructionCloud.FilesApi import FilesApi
from AutodeskConstructionCloud.Models import FileCreateRequest

# initialize the API client
api_client = ApiClient()

# authenticate and set access token
api_client.configuration.access_token = 'YOUR_ACCESS_TOKEN'

# create files API client
files_api = FilesApi(api_client)

# define file properties
file_request = FileCreateRequest(
    name='MyFile.pdf',
    folder_id='FOLDER_ID',
    file_type='pdf'
)

# upload file
file_upload_response = files_api.upload_file(file_request, 'PATH_TO_FILE')

# get file by ID
file_response = files_api.get_file(file_upload_response.id)
