Hatch not showing up

Hi
I’m having trouble with my hatch. I was able to do it totally fine last week and this week when I try to hatch it’s not working - it’s just creating the outline but not actually hatching it. I’ve exited and restarted the app. Any ideas?

Try creating a polyline for the boundary then copy the polyline into an empty area on your screen. Create the hatch there and move it back into the space.

This was me - the layer was hidden… Thanks
