Introduction
|
This is a Superprocess and running it may have an effect on other Datamine files in the project. More... |
This process carries out validation checks on string data.
How to use
The process first renumbers all PVALUEs starting with 1 and incrementing by 1. A new string is started whenever the old PVALUE changes or when the point number (PTN) is 1. This is done in case the input file contains two or more strings with the same PVALUE.
Duplicate points within a string are identified, and the second and subsequent occurrences of any point are removed, except for the last point which can be the same as the first.
Duplicate strings are removed. This is done by summing the XP, YP and ZP coordinates for each string, and identifying strings with identical accumulated values. Therefore strings are duplicates if they have the same points, even though other attributes may be different. It is possible to define two strings which use the same set of points, but in a different order. In this particular case the method would incorrectly flag the strings as identical. If this situation is a possibility then the strings should be checked interactively in the Design Window.
The process PROPER also carries out checks on string files.
