The description of the design parameters shown in the Size (and Parameter) tabs are taken from the DTREF of the SCOM of the CATE in the CATA in the MDS-Standards-Supports (e.g. for an AT01, all the SCOM are collected for /ATTA-AT01). Where the CATE cannot be found, the descriptions are shown as unset, and the message ‘Cannot collect SCOM DBREFS and get descriptions’ is displayed on the status bar. If the CATE is found, but one or more design parameter descriptions are unset, it is displayed as unset.

When the Apply button is clicked, the changes for the selected bore size will be reflected in the applicable row of the Parameters tab.

On returning to the Parameters tab, all the changes made can be viewed together. If these are satisfactory, all the changes can be applied at once to the database by clicking on the Apply button.
