- Curve Tangent
- Rotated Curve Tangent
- Translated Curve Tangent
- Surface U Direction
- Surface V Direction
- Surface -U Direction

Autodesk Inventor Nastran allows you to select the surfaces with a shell mesh in the Geometry section.
Display Options will allow you to change the size and color of the material orientation vector.
The following pages describe the different orientation definition techniques in the Type pull-down menu in further detail.
In composite analysis, a zero angle ply means that it is aligned in the direction of the material orientation.
