Surface face not showing in drawing

[madbrad]

I have a part that was created by using thicken on surface-extrude, and in drawings one specific face of the part isn't showing up. Every other face (made within the safe surface/thicken features) shows up just fine, but this one doesn't show up. You can see the corner of a part that is behind it, and the tangent edges are now showing as an actual edge.
Things I've tried/checked already:
Material/appearance
Transparency
Hide/show part/face/body/surface
Display states
I attached a photo of the drawing view and a photo of the part/assembly in the same orientation so hopefully you can see what I'm talking about.
Any ideas would be appreciated!

Hi madbrad,
Try these:
Tools/Geometry Analysis/...
Tools/Evaluate/Check/..

Hi, something else to try - is display style set to high quality. Might not make any difference.

Thanks for the help y'all.

Changing the view display to Draft Quality made the view look correct but the underlying problem was in the surface thickness. I needed to change the thicken tool from one-side to both sides and that solved the root problem.
