In the menu where you check for Supress Hidden line, there is a checkbox up on rigth side with txt Nonrendable Objects, check that and it will show, but also maybe something you dont want to see.
Workaround if it do is to explode the Hatch and then give it a tiny thickness, then it will show in HL render even if Nonrendable is unchecked.
But of course then its not a Hatch anymore so you cant adjust settings on it etc
