material orientation missing after linear partten

[lambert8809]

Dear All,

I am trying to model a textile composites structure. I have a unit cell (PART-1) with matrix and yarn, and the yarn is orthotropic material. The material orientations are defined in this unit cell. However, the material orientations are missed after I use linear pattern to create the whole structure in assembly module. As can be seen in the attachment, the whole part has coped the features, sets and sections from PART-1 but no Orientations. I wonder if anyone has ever experienced the same problem. Thank you for your advice and suggestions.


Thanks
Xin
