How to set rotate relative to global coordinates, not object ones?

Question

3D

Need help. Combined objects into a group, put the pivot in the center, rotated the whole group. It is required to copy the object and rotate it 180 degrees, and Rotate is rotated relative to objects and not global axes. How to fix it?

Answer 1

call the tool setting window and switch to world there

Answer 2

And it's better to hold down "w" + right mouse button, then check the "object", and then back if necessary in the same way check the "world"

Answer 3

You can combine them and then twirl them as a group
