Adding a Stagger Origin Point

Select a plies group.

The plies group is divided into homogeneous sets of plies that share the same rosette, valid orientation, reference point, and a common area of the reference surface with another ply of the set.

Select a line in the dialog box to highlight the corresponding ply in the work area.

Click COMPUTE.

Stagger origin points are computed.

Used the status and diagnostics from the computation to modify the parameters and restart the computation.

Stagger index, that is, the integer value associated with a ply to define the position of its origin point with respect to the reference point:
- with minimum stagger indices: Only minimum stagger indices are used, that is, 0 and 1.
- with maximum stagger indices: More stagger indices can be used (Listed under Homogeneous set).
  Note: Two linked plies cannot have the same index.
Minimum Stagger Value (MSV): Distance between two stagger indices for an optimum shear strength.
Width of the material (tape width).
Gap between two adjacent tapes.
Minimum nb plies must be located between two plies with the same stagger value in the same homogeneous set of plies.
Tolerance between manual origin point and stagger origin point computed from the stagger index.

Select one or several plies in the dialog box.

Under Point management, modify the Reference point.

Modify Origin:

Modify from Stagger index provides a list of the indices used for the computation of stagger origin points. Select one index to change the current one.

If required, click Export table... to export the result as a file.

When stagger origin points already exist in a plies group, start Stagger Origin Points and click CHECK to verify their validity.
