How to use the fonction Mirror Components and constraints?

[SophieSmith]

Hi,

In an assembly, I have some parts that are symetric to a plan.

The parts are symetric, so it uses the same parts.

I can easely place the new parts with the fonction Mirror Comonents.

But it dosen't copy the constraints, so the new parts move!

How can I block them to the position of the mirror.. so that if I move a part, the mirror part will move too?

Thanks!
