I need to mirror my object using the World Origin as reference but I can't change the object's origin. If I mirror using the object's origin, the mirror is completely wrong. How can I change this? I have tried to modify the origin using edit, origin, and 3D Cursor but it doesn't work. What can I do? I need to use the blue line as reference for the mirror.

  • $\begingroup$ Show an image of the whole screen. We can't see where your 3D cursor is in the image you've posted. You can save an image in Blender via Window > Save Screenshot. $\endgroup$

Simply use another object like an empty placed wherever you wish as Mirror Object if you wish the object's origin to remain unchanged.

In Object mode:
Click on Affect only Origins:

Then move origin using regular tools

Don't forget to uncheck Affect only Origins when it's done
