Why Symmetry doesn't work？

[raymondguo_cgi]

Why symmetry doesn't work on 'front wheel' and 'rear wheel layers', while it works well on 'front light' layer?

The following is my model

I want to do symmetry on the rear wheel layer, but it doesn't work, I turned on the symmetry although, anybody can help me with this? Thanks!

Here is the model file

@raymondguo_cgi Thanks for providing the file.
I double-checked the behavior in Alias 2024.0 and was able to create the Symmetry by activating the layer Symmetry. in your picture you just activated the Folder Symmetry.

I opened the file, and the headlights are not using symmetry. There is actually data on each side of the model for those. If you want symmetry, you have to have symmetry on for the layers underneath the top level folder. You can select all of the layers with the shift key, and then ask for symmetry on those. Then your upper folder can easily turn them all on or off.
