thank you for your answers guy's 
what you do? scale you down vicki or scale you up the carrara things?  Is there no option to get the workspace bigger? 
i did a render and dont scale vicki because she had a lot clothes on but than i choose the sky with the small clouds and the clouds are around her belly piercing (looks funny but not that i want)
that can not be the right way to scale in every scene all poser content down ????? and the proportionen make me mad :-(
any useful advices for me please ?
