I converted the posebox for use with the BodyShop Mechanic
Thank you to Wes H. and Dr.Pixel
To install these poses:
Unzip poses into your Config folder ...My Documents\EA Games\The Sims 2\Config\
Then you will find them on the list of poses next time you run BodyShop Mechanic.
Select the pose you wish to use on the drop-down list, and run BodyShop.
