Generating a DTM of the Pit Design

Exercise: Generating a DTM of the Pit Design

In this exercise you are going to generate a wireframe surface, using DTM methods, for the untrimmed open pit design strings _vb_trc_pit240. This includes the following tasks:

Defining data and view settings
Generating the DTM
Saving the DTM to a Datamine file.

Defining Data and View Settings

Select the Design window.
Select the Project Files control bar, Strings folder.
Select, drag-and-drop the following files into the Design window:
- _vb_trc_pit240
In the Sheets control bar, Design Overlays folder, select only the following overlays (i.e. display these overlays):
- Default Grid
- _vb_trc_pit240 (strings).
In the View Control toolbar, click Zoom All Data.
In the View Control toolbar, click View Settings.
In the View Settings dialog, define the Section Orientation and Mid-Point XYZ coordinate (6040, 5040, 100) and other parameters shown below, click OK:
In the Design window, check that your view is as shown below:

Generating the DTM

In the DTM Creation toolbar, click Create DTM.
In the Make DTM - General Options dialog, Output group, select the New Objectoption, enter the name 'trc_pit240tr'.

Saving the DTM to a Datamine File

In the Loaded Data control bar, right-click on the trc_pit240tr object, select Data | Save As.
In the Save New 3D Object dialog, click Single Precision Datamine (.dm) File.
In the Save New Strings dialog, select the path to you tutorial folder, define the File name: as 'trc_pit240tr.dm', click Save.
In the Loaded Data control bar, check that the trc_pit240tr object has been replaced by trc_pit240tr/trc_pit240pt(wireframe).
