In order to determine the thickness offset used when calculating plate shapes and to determine weights of parts in the design, it is necessary to specify material types for frames, decks, stringers and plates. These materials are stored in the Workshop Library and can be edited using the Edit Materials… command from the Edit menu.

To add, edit or delete a material:

Ø        Choose the Edit Materials…/Materials Library from the Edit menu

A dialog box will appear displaying the materials in the library

To remove a Material:

Ø        Click once on the material's name in the list of materials to select it

Ø        Click on the material's pattern to edit it if you wish

To save your changes to the materials:

Ø        Click the OK button

The materials will be saved in the Workshop Library when you quit Workshop. They are saved along with the stringer shapes and cutouts, and will be available next time you use the program. Some of the material properties (Strain Limit, Sheet Width and Sheet Length) are not used yet, however they will be used in future versions of Workshop.
