hi

I try your option, it is ok. save arm and export and than import again, work perfect, but I have to change all the names and groups. because now the 2 arms skeleton has the same name

so I have to go every single ik-joint-handle-controle change the names. that is alot of time and some of them when you change the name doesn't work.
time of changing the name's from left to right=I can build new arm skeleton

your idee is great but not really for complex skeleton joint.

also easy way not just export ther arm and import again.
just select all joint with ik and handle's and duplicate and flip -1=X

but still i have to change the names. but in maya 8 it is great option for mirror you can change all the names from left to right or others. but this option is only for joint.

thanks again. any more idee? welkom please
