issue with wall layers

[NeilLaura]

Having issues when I go to build this wall it keeps showing the studs and not showing the outer layer of drywall. I have it being built as one continuous wall from the window on the left, everything looks good until I add the opening. Any ideas

Thanks Neil

My guess is that your wall layers are messed up.  Either that or your wall surface material is transparent.  If you can't figure it out, you might want to post the plan.
