As I’ve been working on my first Q&A, I’ve found errors to fix and improvements to make in the underlying document. I’m not sure how I push the revised document to the Q&A in progress – or is this not necessary to do?
Not necessary! Just save changes in your library clause or in the underlying document, and they will show up automatically in the Q&A. (You can even edit library clauses directly from within the Q&A by double clicking on them within the Design Q&A environment.)
(Be aware that updating an adhoc clause is not enough: you will then also have to save the document it is contained in.)
