piston not working.blend (1.5 MB) and how does this work?

To see if from the front: press 1 on the number pad
to see it from the left side: press 3
to see it from the top: press 7
to see it from the back: press ctrl+1
to see through the camera: press 0

is this what you mean?

something messed up the post!
i just need to know how these work in 2.69

So, you’re trying to see if the file works in 2.69?

sorry, I no longer have a copy of that.
