Yes, that does work very well. In my case, I generally create a single PDF rather than a separate file for each part. I don’t see a direct way to do this with Dorico’s export.
That is possible with PDFCreator, as PDFCreator gives you an opportunity to merge the separate PDF files before saving. There is a problem with that, however, in that the timing of things causes the parts to appear in a more-or-less random order. I would normally save the parts in score order within the final PDF. PDFCreator gives you the opportunity to change the order of parts before saving them. I do that with Finale easily because the parts appear to PDFCreator with identifiable names (Flute 1, trumpet 2 etc.) However with Dorico using PDFCreator, all the parts appear with the same name “document…”, so I cannot see how to order them.
It is no big deal. I can take the parts into PDF Architect (or a similar program) and reorder the pages. It is just an extra step. it would be nice if the PDF export in Dorico included the option to append all the prints to a single PDF, and to do so in the same order as the layouts appear on the left of the screen.
