Push/pulling a curved surface

#1

Hi, I’ve just realised the dimensions of my object are off so i want to adjust them by using the push/pull tool, however it won’t work on the big shaded blue region because it’s bounded by a “curved/smoothed surface”. Is there an easy way to push it up?

Cheers in advance.

FYI, the blue faces are reversed. They should be facing inwards.

Wow, i didn’t realise the faces had orientations. I just reversed the faces and then i could push/pull as normal. Thanks!
