Define Materials
To define material (soil or rock) properties, select Define Materials 
from the toolbar or the Properties menu.
- You can define any number of different material types in the Define Material Properties dialog, by selecting from the list of materials at the left of the dialog, and defining properties for each material.
- Properties can also be imported from other Slide2 files, using the Import Properties option in the Import sub-menu of the File menu.
Material Name
The Material Name you enter in the Define Material Properties dialog will appear in the Assign dialog when you are assigning the material properties. Therefore use a meaningful name which you can associate with your soil type (e.g. "upper clay" instead of "soil1"). It will also appear in the tabs at the top of the Define Material Properties dialog. Note: duplicate material names are not allowed, each material name must be unique.
Material Colour
The Material Colour and Hatch pattern you choose in the Define Material Properties dialog will appear in the Assign dialog, beside the Material Name.
