Something about axis

Hi,
I found a problem is that if I have 2 axis in front of some object and rotate X for -90 in the first axis and also rotate X -90 in the second axis.
Then the Y and Z rotation in the second will be the same. You can see it in attachment.
So is this a bug?

Best Regards

Welcome to the world of Gimbal lock and Euler rotation orders. This is a common problem with Euler rotation in all 3D softwares. The way to resolve this (apart from moving to quarternion rotations) is to define the rotation order. This can be done in the axis properties.
