change local coordinates system of bone

[Andrea Gargamelli]

Hello everyone,

I would know, if is possible the changing of local coordinate system of the bone and in case how can i change them.
I tryed changing the value on model .xlm file, but if I don't mistake there I can define only the position of bones or muscles relative to principal coordinates system of virtual model.

I'm my case I would move the origin of local coordinate system on the center of mass of femur and rotate the axes respecting a precise protocol.

Thanks all
Andrea

Hello!

Maybe you can put the mass center of femur in (0,0,0) and rotate the femur orientation to respect your protocool and of course change also positions of all other bodies in the model?
