Local reference system

Hi,
my thesis work is based on the study of the damage of composite materials. My problem is to set correctly the reference systems of the 3 parts of the component, in particular of the area called 'anima centrale'.
If someone could help me I would be grateful.
Regards,
F

Re: Local reference system

the vector definited by ANG_REP or VECTEUR don't must be perpedicualr to the surfaces group in the all group., never  for each element.
The projection of vecteur on the suface element determines the X axis . The Z Axis is along the normal of surface. Te Y axis i perpendicualr to X  and Z.

Re: Local reference system

Hi,
thank you for answering.
My problem is to define the orientation of the Z axis, which changes according to the element considered.
ANGL_REP or VECTOR allow me to change the X and Y axis, but not Z axis.
I am attaching the geometry's image for better understand the orientation of the elements.
