How to fix a sunkin in face?? on a symetrical mesh (Noob)

I have a spaceShip that is symmetrical on both the left and right sides. But there are two faces on the left side that are sunken in. It should be flushCW-League-DestroyerClass.blend (1.25 MB). Is there a tool I can use to fix that, so It matches the other side?
I tried screwing around with the Mirror mod, but I couldn’t get it to work.

Its very subtle, most wont notice, but it bugs me lol… I didn’t mention the locations so here it is: If looking from the (Left Orthographic view) the rear GREEN and GREY faces behind the connecting bridge. Its triangular in shape, and there on top of each other…Once you spot that, if you look on the opposite side of the ship, you’ll notice the difference, the left side panels (green/grey) appear to be slightly sunken in. Thats the part I need fixed.

Sorry for double post

in the mesh menu when in edit mode there is the symetrize option, though i think it requires equal vertices on both sides.

Moved to Support > Modelling

And that’s why it’s a good idea to attach a full resolution screenshot that shows exactly the place and position in the whole model, instead of uppercasing normal words.

I think I found it was hard to look for it , anyway you have 2 faces on top of each other there just select the face and delete it .

I’ve just looked at the blend file, I’m no expert but it looks like their normals are reversed. In edit mode Just flip the normals of the faces and it should be OK.

Wow thank you so much everyone!!! Flipping the normals was the way to fix it :slight_smile: I really appreciate it everyone :slight_smile:
