Material Directions 1, 2, and 3
For material directions 1, 2, and 3, you observe or specify any of these values, depending on the model type and material orientation:
• the axes of the referenced coordinate system
• one of the solid directions
For 3D material orientations, you select one of the following six combinations of the current coordinate system directions for the three principal material directions:
Material Direction:
1
2
3
Coordinate System Direction or Solid Direction:
X
Y
Z

Creo Simulate automatically changes the label above the third column of check buttons from Z to –Z when necessary to reflect the fact that the material orientation is right-handed.
 
* The material directions 1, 2, and 3 correspond to the directions understood on the Material Orientation Definition dialog box when you enter orthotropic or transversely isotropic properties.
When you click a Material Direction option button:
• Creo Simulate redraws the material orientations.
• The displayed material directions differ depending on the option you select on the Relative To menu.
For an example of material directions, see Example: Material Directions.
