Reversed Faces Issue

When I draw an object, i.e., a rectangle, the bottom face is on top. Any clue what I’ve done to make this start happening? I haven’t used SketchUp in a while, but I don’t think it happened before.

It has always been that way as the software expects you to pull it up to form a 3d object.

Thanks! Guess it shows I haven’t used it in too long a while!!
