The 3D Interaction Surface view includes many of the same chart functions as the 2D view.
- Section – use the drop-down menu to select the pile section displayed.
- Graph Type - Use the check boxes to toggle ON/OFF the Unfactored and Factored graphs.
- Pan/Zoom – use the pan and zoom tools to adjust your view of the 3D Interaction Surface
- Diagram Settings – adjust the transparency of the graph using the Diagram Settings on the left.
- Report Generator - like all views in RSPile, this specific snapshot of the 3D Interaction Surface can be added to the Report Generator by selecting Add View
Unfactored/Factored Table
In addition to the 3D view, a table showing the maximums and minimums of the surfaces are also given.
