Hello, I am a newbie to CST Studio Suite. I am practicing drawing an array of objects as the attached figure 1. In here, I am using rotation transformation in CST microwave studio to rotate a unit cell to ten unit cells, but, the slit angle of the unit cells is changed following the rotation transformation. I would like to draw an array of unit cells that do not change the slit angle direction in attached photo 2. Could you give me some ways? Thank you so much!
