Cat® Terrain v6 for Grading and Loading Caterpillar

• DXF Color (non-hatched)

• Hatched color

• Mined-out polygons

• Bitmaps

• Extended Material IDs

DXF Color

The following settings in the MCU are used by the on-board software to identify materials by relating the DXF color of a polygon to a corresponding description:

• "DXF Color"

• "Description"

Note: Use consistent colors and descriptions in both the on-board software and Cat^® MineStar System.

Reference: For additional information, refer to Systems Operation, RENR9562, "Cat^® Terrain Office Software".

Hatched Color

The Plan window is limited to a background color and 15 additional colors. Each color is used to represent a different material. Only 15 materials can be represented before a color is repeated for another material.

By applying a wide hatched pattern to the fill color that is used to identify materials, 30 materials can be identified from the Plan window.

To prevent confusion with the hatched pattern used to indicate Mining in Progress areas, the pattern used for material identification is less dense.

(1) High Grade Ore defined by red area that is not hatched (2) Low Grade Ore defined by red hatched polygon

Illustration 1 demonstrates polygon hatching used to differentiate materials that are identified by the same color.

Note: The configuration of the hatched areas should be the same for all the machines that are on the site.

Mined-Out Polygons

Using the on-board software and Cat MineStar System, polygons that are used to designate mined-out regions can be included in DXF files. Any polygon with a DXF color in the range 240 to 250 will be interpreted by the on-board software as a mined-out region. The on-board software will show these areas as mined-out on the Plan View.

Bitmaps

Bitmap images can be used to create a customized color pattern.

5 KB Bitmap

Illustrations 2 and 3 represent two different scales that are using the same custom 5 KB bitmap. The bitmap was placed in the caes\data directory on board the machine. In the MCU, the color red was described as "Hi Grade" and associated with the bitmap. On the machine, the bitmap appears and the loaded dipper shows the underlying material as red.

The swath options were used to set up mined out and mining in progress areas. The mined out areas appear with both the bitmap and underlying color removed. The areas that indicate mining in progress appear with dense cross hatching.

Extended Material Identities

Materials identities can contain two components. The first component is a base material name. The second component is an extended material identity. The base material name is determined from the DXF color of the polygon. The polygon defines the material region in the material map. The association of DXF color to base material name is established using Cat MineStar System.

An extended material identity is associated with a single material polygon in a DXF file. Each material polygon can have an extended material identity. Extended material identities are text strings that are contained within the material polygons. In order to be interpreted as extended material identities by the on-board software, the text strings must conform to the rules below:

• The text location (x, y) must lie inside the polygon.

• The DXF color for the text must be 230.

• There must be only one text identifier per polygon.

• The text must be in the DXF file with the material polygon.

• The DXF layer with the text must be converted as a Display layer in Cat MineStar System.

The tag <h> is added to enclose hidden text.

Long extended material identity text strings can cover a large part of the display. Use hidden text to keep information off the display but still have the text appear in reports.

For example, "Hi in Gold,<h>0.3,0.2,0.7,<h>103" in the DXF file appears as:

• "Hi in Gold,103" on the display

• "Hi in Gold,0.3,0.2,0.7,103" in the reports

Material polygon design with extended material identities

In Illustration 1 two material regions have been created. Cat MineStar System uses the color of the line work of each polygon in order to define the base material name. The text within the polygons defines the extended material identity for the base material. A tilde is used to separate the base material name and the extended material identity.

ore~Hi in Gold, 0.3, 0.2, 0.7, 101

The extended material identity can contain material parameters. Material parameters provide additional information about the base material. The on-board software can be configured with the capability to extract the parameters from the extended material identity.

The background can also be associated with material parameters. Background parameters cannot be the same as parameters used in any polygons on the design. If background parameters are used, the polygons are not clear.

Reference: For detailed information on configuring the on-board software for extracting the parameters from the extended material identity, refer to "Material Identification" section of this manual.
