Hidden geometry

[Deeferdaz]

I keep trying to extrude on my drawing and it won’t let me. Keeps saying new geometry hidden by sketch view. So the question is what is it. And what have I done to make this happen. And is it reversible thank you

Hi! You’ve accidentally turned on Section View. To turn it off, please tap on the orange section view icon in the lower right
