Laminate Composites > Defining plies and a stacking sequence

Using a spreadsheet or a CSV file to define a layup

Use the Edit Layup in Spreadsheet or Import Layup from CSV File options to define your layup in an Excel spreadsheet or a CSV file, and import the layup.

Each row in the file defines one ply in the layup. Each column cell in the row specifies a property for the ply. You must specify the columns in the order shown in the following example.

Material Name Thickness (mm) Angle (deg) Description
KEVLAR SKIN 0.0635 0
KEVLAR SKIN 0.0635 –45
KEVLAR SKIN 0.0635 90
KEVLAR SKIN 0.0635 45
KEVLAR CORE 12.7 0 Core ply
KEVLAR SKIN 0.0635 45
KEVLAR SKIN 0.0635 90
KEVLAR SKIN 0.0635 –45
KEVLAR SKIN 0.0635 0
  • The material name is the name of an existing Pre/Post material or ply material. If the material name is not found in the FEM file, the ply is not imported.

  • Thickness values are in the FEM units.

  • The orientation angle can be a positive or negative value in degrees.

  • The description column is required but entering a description is optional.

To import the layup from the spreadsheet, select the cells you want to import.

Note:

When you import a layup into an existing layup, it overrides the layup definition.

When you import a layup from a spreadsheet or a CSV file, the Stacking Recipe list is reset to Regular. The content of the ply layup is always identical to the content that is displayed on the Ply Sketcher tab.
