Introduction

The basic unit of data in a MineMap IMS CAD file is the point. Each point has the following values associated with it:

Table 1: Point attributes

Value / Notes
Easting
Northing
Elevation
Point Number / A unique integer used to refer to the point when it is used in a string or as an anchor point for text. Point numbers must increase through the file.
Comment

Most functions in the 3D View Pane deal with points, at least indirectly.

Menu ITEMs
