HELP! Flattened object?

At some point i had something selected off screen and it flattened (an airplane wing) along one axis and now i can’t seem to move the vertices or planes outside the Z/Y axis. They literally will not move into the X axis. All my vertices are there and i just want to pull it apart again, but it’s not letting me.

I don’t understand.

With a 0 scale on any axis you will be able to move your vertices on this axis but the 0 scale will center them over object’s origin.
“Apply” the scale of your object or fix the 0 scale.

i dont understand what you are saying? Apply? are you saying “apply scale”?

AHHHH you fixed it

my scale on my airplane wing had been set to 0 for some reason. I never intentionally clicked that, and when i set it to “1” it fixed everything
