I have imported a Finale documenta to Dorico, thein separated intolerant 4 flows
How can I change the bar numbers so that the second flow starts alain with bar number 1
Form the moment bar numbers continue strait throught the whole piece
Right-click on the first measure and select Bar Numbers–Add bar number change. Set it to “1.”
When you split a flow, the new flow will automatically be renumbered from bar 1, so that suggests something else must be going on. It may be that for some reason there are already bar number changes in the project. But, as usual, I would need to see the project itself to be able to say what might be going on.
