Create Nodes at Elevation

Tip

Use this tool to create entry points for each bench in the pit or dump. 

To create nodes by elevation: 

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Centre the pit in the Network tab.

  4. Hover the mouse over the pit floor and read the RL from the status bar in the bottom left of the screen. This should be 1030.

  5. Hover the mouse over the ramp crest and read the RL from the status bar. This should be 1120.

  6. Double-click the pit ramp to select the entire length.

  7. Right click > "Create Nodes at Defined Elevations" > "As Bench Exits".

Node Naming

Nodes must have the unique names in HI and names must be the same as other systems in some cases.

  • If you are processing a schedule, the nodes must have the same name as the schedule sources and destinations.

  • If you are interfacing with dispatch, the nodes must have the same name as they are called in the fleet management system.

This means that nodes must be renamed from their default names.

To rename nodes in the Properties panel:

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Centre the pit in the Network tab.

  4. Drag a box over the pit to select all pit nodes.

  5. Open the Properties tab below the viewport.

  6. Change the selection type to "Node".

  7. Edit node names in the Name row.

...

Nodes can be renamed with formulas in Microsoft Excel. For this, you’ll need to export data in CSV file. Use Export button > “Nodes & Segments to CSV” option.

Dump Time at Nodes

Tip

Every node has a SpotAtDumpSeconds property which controls the dump spot time at that location. For example, spot time at the crusher may be different from spot time on the main dump.

Set spot time at the crusher:

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Open the Nodes panel in the bottom left of the screen.

  4. Select "Crusher" in the list.

  5. Go to the Properties panel at the bottom of the screen.

  6. Change the SpotAtDumpSeconds from 30 to 50 seconds.

...

This will increase the total cycle time of the truck by twenty seconds.

Using the Nodes Panel

Tip

The Nodes panel is where nodes can be organized into groups for finding, hiding and editing.

...

Organizing nodes by property:

  1. Navigate to the sample data \NodesVersion folder.

  2. Open SampleModelWithNodes.hinf.

  3. Open the Nodes panel in the bottom left of the screen.

  4. Clear the Grouped Fields by dragging each row into the Available Fields list.

  5. To organize the Nodes by their type, drag "NodeType" from the Available Fields list into the Grouped Fields list.
