Hello, hope someone can help me ! I am really new to Affinity Designer (used to work with Indesign). I started to creat a document, since I was about too creat a pdf with a number of pages, I copied the cardboard several times. So Now I have about 40 dartboards, I worked with them, like they were double pages. I arranged my photographs on the "double" pages and then start to arrange my "double" pages / artboards ... so at the end I got the right order, so my new portfolio work out for me. NOW TO MY QUESTION : When I export my document as a pdf, the pdf will take the order of the pages/artboards like it was in the beginning ??? I really don#t get the advantage of that ? I mean I did the order by dragging the artboards around on purpose, so of corse I want it like that in the Pdf and not the order from the beginning where I had my plain dartboards without any pictures included ? I hope someone understand my issue and can help me :-) Thanks a lot !! :-)
