Introduction

Plots the intersection of a block model with any plane.

How to use

The plane may be specified by its centre, size, azimuth and dip; end points and vertical limits of a vertical section; corner points and RL for a plan; or a section from a standard section definition file. The polygonal outlines, representing the intersections with model cells and sub-cells, may be colored using a model file field; shaded or solid colour filled using intervals on a model file field with an optional legend; or annotated with one or more field values or a symbol.

Features of PLOTMX include; shrinking of block outlines; annotation of up to 10 fields offset from one of 5 reference positions; default and user defined titles; icon showing the orientation of the plane; legend; plotting of grids and control of character size and color for annotations, titles and other plot components.

PLOTMX may be used for reproducing views of a block model with additional annotation options. Plots from PLOTMX are particularly useful for superimposing when creating outlines for underground design and stope evaluation. It adds to Datamine the ease of producing views of a block model on any general plane.

The process will accept a block model which has been defined using the Rotated Model option in PROTOM. A message will be displayed to show that the model has been identified as having the reserved Rotated Model fields. The main restrictions when using rotated models are that the position of the annotation must be relative to the cell centre, and vertical exaggeration is not permitted.

Definitions

A 'box' is defined as the intersection of the specified plane with a model cell or sub-cell. Such boxes may be irregular in shape if the plane is oblique.

Input

No

Undefined

Examples

Example 1

This example illustrates the cell annotation features of PLOTMX. Two fields are annotated with different character sizes offset from a centered symbol. The plane is a north-south section specified by its end points. The section is scaled into the data are as specified by the plot prototype and the icon is plotted in the margin area.
