Support Modeling
1

I have very boring problem, when i rotating object too often and changing views, scaling object down, then after some time every controls of that object are messed up, i cannot zoom in properly and i cannot rotate as often then all of the axis turning into different direction, Alt R not always help and changing view to local or orthographic also.

How to avoid this ??
