Read a saved Legal Opinion, QnA or Analysis first. If it gives you the right starting point, choose Create draft from this beside your notes. Draft opens with that answer in Case Details as readable text. You can edit it, give the draft a title and choose the files you want to use. Nothing is generated until you ask for the draft.

This handoff carries the saved answer, not the original question or its attached files. Check the details before you run it, especially names, dates and what you want the draft to say.
