Thanks, Callum, and apologies for my perceived impatience. I added a thread to Feature Requests this morning.

intelligent_rulers_upd2.afdesign
 
Because some are waiting tooooooooo long for better rulers including a “change origin point” feature,
we made a flexible ruler for dm, Berthold points, Pica points, Didot points, DTP Cicero and other units that you can change easily for your own needs just in seconds. Even if you need furlong, light-nanoseconds, Fournier point … no problem.
 
Now you can have many rulers with different units at the same time. And they even can measure curves. Some backgrounds can be found somewhere.
 
Have fun and help to improve Affinity apps.

Hi Henry,
 
Welcome to the Forum :)
 
Please could you try exporting the PDF to your desktop to see if it then allows you to export? If this does not resolve your issue could you please send me a private message through my profile so I can look into this further for you? 
 
Thanks
C

herbz,
 
This is a public forum so nothing you post here is private. If you are concerned about the content of your screen shots, I think you can edit your post to remove them.
 
For an issue like this, just the screen shot of the error message window would suffice to demonstrate it (& would result in a much smaller file that is easier to see & takes much less time to display).
 
Also, from your second screen shot, it seems you are trying to save the file to Apple's iCloud servers. Try saving instead to any local folder in your user account's home folder.

Hi herbz,
Welcome to Affinity Forums :)
I've removed the screenshots from your post to keep them private.
Please follow Callum's advice to check if the file can be exported to desktop. If you need to share more screenshots you can upload them to a Cloud service and share the link with the staff through a PM (personal message).
