How to mirror an object across another

[Anonymous]

New Maya user, I previously used Blender.

I am just wondering if it is possible for me to mirror an object basing on another.

For example, I'd like to mirror this wing of the plane across the body of the car, i.e. the object I highlighted in blue.

So far, I tried to change settings in mirror position, but it doesn't work as expected, so I have to manually adjust the offset. But then when I enable symmetry, the mirrored object does not update when I change one side. I guess because of the offset isn't precise.

Anyone know the solution to this problem? Many thanks!

Not directly.

A] Long, lossless way:

1. duplicate the object you want to mirror - O1 (ctrl+d);

2. duplicate the object you want to use as pivot source - O2 (ctrl+d);

3. parent O1 under O2 (shift-click O1, O2 and press p);

4. scale the O2 -1.OOO in desired direction;

5. unparent O1 (shift+p), delete O2;

6. freeze scale transform (Modify->FreezeTransformations[]).

B] Short, lossy way:

1. align O1 pivot (shift click O1, O2 Modify->MatchTransformations->MatchPivots);

2. select O1 and shift+RMB->Mirror[];

If you need this often, then you might wish to search for some duplication scripts and save as shelfButton/hotkey.

Hello! Thanks for the reply! It worked like a charm!

Btw, sorry to bother you again, so after I mirrored my object 1 across object 2.

When I enable symmetry, the change does not update to the other side, it is like this.

I tried all symmetry option, whether world or object, but nothing worked so far😢

Just wonder if you know how to fix it? Many thanks again! 😄

Is this single object or two separate? Won't work on two separate objs, thus Mesh>Combine. Or if it already is a single mesh, then make sure it is really symmetrical - you already know how to mirror....and choose the Symmetry options ObjectX.
