Probably the easiest is to use [SetAxesWorld() method](https://apidocs.slicer.org/main/classvtkMRMLMarkupsPlaneNode.html#a586879796afd9f81187c3c8333370f51).

To get answer for questions on basic Python syntax, I would recommend to ask an AI chatbot, such as Microsoft Copilor or ChatGPT. For example:
