Assign Materials
The Assign Materials 
option is available when in the Stope Section view and allows for the graphical selection of abutments to assign material properties to.
To assign the material types you have defined in the Material Properties tab of the Input Data dialog, to the various abutment segments of your pillar model:
- Select Assign Properties from the Boundaries menu or right-click menu.
- In the Assign Properties dialog select the material you would like to assign. Notice that the material name and colour are those which you defined in the Material Properties tab of the Input Data dialog .
- Now simply click the left mouse button on the abutment line segment in your model, and you will see that the region will change to the colour of the assigned material. Repeat this step to assign the same material to other abutments of the model if necessary.
- If your model has multiple material properties, repeat steps 2 and 3 to assign the desired materials to all abutments of the model.
- When you are finished assigning materials, select the X button to close the Assign Properties dialog.
TIP: To quickly assign Material Properties to multiple abutments, for Step 3, click the left mouse button and drag the box over the abutments. Any segments within (or partially within) the bounding box will be assigned the currently selected material property.
