man diffpos (Commandes) - compare the contents of two .3d files
NAME
diffpos - compare the contents of two .3d files
SYNOPSIS
diffpos .3d file .3d file [threshold]
Description
Diffpos reports stations which are in one file but not the other, and also stations which have moved by more than a specified threshold distance in X, Y, or Z. The threshold distance is given in metres and defaults to 0.01m if not specified.
For backward compatibility diffpos will also read the .pos files produced by earlier versions of cavern, or by 3dtopos.
