Well, I think I didn't make myself clear, sorry. Just a little explain: example, when a plane is translated like (X, 0,0), it gets smaller and upper (seems like the translation made is by (X, some value of Y, some value of Z).
Here is a sequence of images, to explain:
See that the first plane (left most) is correct. But the others, which supposed to be at the same Height and Depth, are shifted.
I've tried many things and nothing worked at all. What I want is to align them at the same horizontal axis, like if they were 3 buttons at the screen.
