Thank you for your contributions and valuable insights!
Your answers highlighted several use cases for varying detail levels on a single drawing: for example, Renovation, Refurbishment, and Security drawings.
We would like to investigate these use cases further. If you have plans and documentation that show such use cases (that is, doors and windows with different detail levels in a single drawing – e.g. existing windows are simple, and new windows are detailed), and if you are happy to share them with us, please leave a comment, and we will contact you directly. Thank you!
