Defining Material Orientation for Volumes
To define the volumetric material orientation, specify the following items:
• Relative To—Specifies the reference
coordinate system for the principal material directions.
• Material Direction—Specifies the material direction. This area includes:
◦ Material Direction grid—Use the buttons in this grid to select the alignment axis for material directions 1, 2, and 3.
◦ Rotate about...—Specifies additional rotations about one or more material directions.
• Preview References—Specifies the geometric components for which you want to preview the material orientation.
