gameobjects change size and directions when parented

Unity Engine
1

it ocurrs that when I parent a plane to another plane then the whole direction axis is reset.
example:
-the plane has an inclination of 25 degrees but in the inspector the whole thing is reset, everything says 0!
-the plane I had just explained before has another problem, it ocurrs that when I want to make this plane back to the way it was using the rotate tool everything “works” allright but if I use the inspector to rotate the plane it suddenly rotates in another way and changes his size up to 400% of his of his last seen size.

need some help, I got the unity 3 and I think this may be some king of glitch.
and yes; I am clicking the gameobject that I am describing.

I appreciate the help.

don’t change the child plane before you parent it, change it after you have parented.

Also, are you sure you are working in the correct axis, e.g. world vs local?

The position, rotation and scale are the relative offset from an object’s parent.

i.e. If the parent is at 0,0,5 and the child is at 0,0,15 then the child will show up as 0,0,10.

well this explains quite a few things from unity 3 but the problem remains with the inspector and the enparented “plane”, somehow this glitch only works on planes, I am going to try to cubes to make my scenes.

thanks everybody who colaborated.
thanks.
