The illustration shows the top 3/4 view of my models bone structure. As you can see. everything is symmetrical. The red lines represent the arm beginning at the shoulder joint. When I first placed the bones, if I used the duplicate with symmetry command I would get a perfect mirror image. Now I get a perfect mirror image but it seems now Carrara is using a different angle to mirror the bones. How can I control the axis that Carrara uses to mirror the item. The selected blue area is where Carrara is placing the arm, the red area represents where I expected the bones to be using the command. Dose this make sense now? English is my second language so please bare with me.
