Two features are very useful for checking the lay-up definition before solving the model. One is the Orientation Visualization, the other is the Section Cut feature.
The Orientation Visualization can display the direction and/or orientation of the elements, Oriented Selection Sets, and plies. Refer to Scene Manipulation for more information.
After the whole definition of the lay-up, a visual verification of the lay-up sequence can be very useful. Section Cuts offer a useful visual check once the lay-up has been determined. By defining one or several Section Cuts, the ply position (number in the sequence) and orientation can easily be verified. Refer to Section Cuts for more information.
