The final step in creating a Slide model is to:
DEFINE all of the material and support properties, and then
ASSIGN these properties to the various elements of your model.
Properties are defined using the Define options in the toolbar or the Properties menu (e.g. Define Materials, Define Support). Properties can also be imported from other Slide files, using the Import Properties option in the Import sub-menu of the File menu.
Properties are assigned with the Assign Properties option in the toolbar or the Properties menu. If you do not assign properties, then default properties will be in effect for all elements of your model (i.e. soil regions, support, and tension crack).
The Default Properties are the properties of the first material in the Define Materials and Define Support dialogs. The Default Properties are in effect until you use the Assign Properties option to assign other properties.
