Define a Rosette
A reference coordinate system that defines a reference direction for the ply and core orientations.
You must define a layup surface before defining the rosette. To learn how to define the layup surface, see Define the Layup Surface.
You can define multiple rosettes in a Composite feature. The last rosette defined is set as the default rosette and it is identified by 
.
.Define a rosette as follows:
1. Click 
Rosette. The Rosette Coordinate System dialog box opens.
Rosette. The Rosette Coordinate System dialog box opens.2. Click on the layup surface to place the origin. A preview of the rosette coordinate system appears in the graphics window.
3. The default offset type is Linear. To change the type, from the Type list, select Radial or Diameter.
4. To select offset references, drag the offset handles to references, or click the Offset references collector and select offset references.
5. To orient the coordinate system, click the Orientation tab.
6. The Z-axis lies along the stacking direction. To orient the rosette coordinate system, align the X- or Y-axis as follows:
a. The Use collector displays a reference to orient the second direction. To change the reference, click the collector and select a new reference.
b. From the to project list, select the axis to orient along the second direction.
c. To flip the second direction, click Flip.
7. Click OK.
Change the Default Rosette
The default rosette is automatically selected when you define plies and cores.
Change the default rosette as follows:
1. In the Composite Tree, select the rosette to set it as the default rosette.
2. Click
