How to fix mirroring issues? Trying to mirror but object rotation is wrong I am trying to mirror across the global YZ plane, so have been using the mirror tool set to the X axis. My pivot point is set at the 3D cursor at the origin. However, when I mirror, the mirrored object is in the right location but its orientation is wrong. It is not mirroring across the right plane. I tried using global axes as the mirror reference or the 3D cursor (Set at the origin). In the attached screenshot is a photo of what is happening (3D objects) versus what I want (drawn in red)
The Mirror modifier uses the object's local orientation, you must have rotated the object in object mode, so its local orientation is not aligned with the global orientation anymore. If you want the Mirror to be aligned with the global orientation, apply the object's rotation with CtrlA &gt; Apply Rotation.
