I use Affinity apps to design work that I render on a laser. In order to cut images out I need to trace the outline with a red hairline. At the moment I do it in Corel Draw where the laser resides. It would save me a lot of steps/time/work if I could create the red hairline in one of the Affinity products. The ability to do this would also help make the case for getting the iPad version of Affinity P&D .

. . . and you pointing out "failing" is a very negative approach to my post.

If it's showing upon document creation... seems like you have one margin set. The left one at 1".
Go to File > Document Setup > Margins Tab and uncheck "Include Margins". Or zero it out.
 
For new documents make sure the margins are off on the original setup page.

How do I batch process a set of images with all of the same effects?
