For all those interested in importing Corel Xara files from their Designer package I have managed to do that. If you have a relatively recent Xara Designer app then you can export a PSD file form their app. You can then import it into the Affinity Desgner 2 (possibly Designer 1 but not tried that yet). Your options in exporting include selected or the whole page. I would just opt for the selected option after you have highlighted the features you need to transfer. Opting for the whole page exports a much larger file and may have confused anyone trying to import it as I found with my first attempt. The file loaded with the graphics visible only in the top right hand corner so the centre is off page to the top left. AF Designer only shows what is on the page so you could have missed them. By selecting two pages from the the graphic items in AF (which I assume is the whole screen and the files 'page' then deleting them - I was able to reduce the AF page size and select around the top corner of the screen which highlights the invisible parts of the file, group them and drag them onto the AF page.
It would help if Affinity scaled the imported image to fit the page size and positioning it centralised on the working AD page. That would keep it visible and allow users to access/modify.
I can now import any Xara files from my vast, like many other Affinity/Xara users, array of files built up over the years.
Hope that helps anyone in the same position as me.
