Quality Code Exchange

A plate part is always created to be of a certain quality (grade). The natural choice is to nest a part on a raw plate with the same quality as the one specified for the part. However, if there is available space on a plate with a different (normally higher) quality it may be allowed to nest the part on that plate.

In AVEVA Marine it is possible to specify the qualities that are allowable to be used for a plate part of a given quality. This is done via a text file in a simple format.

The allowable exchange must be specified individually for each quality. Each quality is corresponded by a "record", starting with the current quality, followed by all the qualities it can be exchanged for, separated by commas (,) and terminated by a semicolon (;). The order within the list is arbitrary.

The complete name of the "exchange file" should be assigned to the environment variable SBH_QUALITY_EXCH. This file may be checked for correctness via the inithull utility.

An example of the layout of the file is given below

In general the qualities to be used must be defined in a text file specifying also the density. See the on line documentation Hull Detailed Design, Setup and customization, Miscellaneous, Customer Set-up of Material Qualities.
