DRAW User Guide

Update : System Update

There are occasions when the database needs to be updated specifically, as opposed to the routine updating that occurs from time to time in normal use. System update explains when and how this should be done.

Update picture files can be carried out to recover from a corrupt picture file, or if an attempt has been made to display a view created using a previous version of DRAW.

Annotation graphics are always restored but Design graphics can not be restored. In all cases, a message alert displays instructing the user to proceed with the update operation, this is the only time that the update should be processed.

To update picture files, on the Update tab, in the General group, click Picture.

To manually update backing sheets with database changes, on the Update tab, in the General group, click Backing Sheet.

Update Template Instances

Update template instances scans the database hierarchy and updates all parts of picture files that use the graphics ‘instancing’ mechanism.

To update template instances, on the Update tab, in the General group, click Instances.

Cross-Database Reference Attributes

Update cross-database reference attributes updates all DRAW element attributes that refer to elements in the Design database. The settings of the attributes exist as database reference numbers.

The update function operates on the current element. It should only be used if the Design database has been deleted and rebuilt from macros.

To update cross-database reference attributes, on the Update tab, in the General group, click Refs.

Cross-Database Name Attributes

DRAW elements with attributes that refer to elements in the Design database (the settings of which exist as database reference numbers) also have (hidden) text attributes set to the names of the referenced elements. Update cross-database name attributes updates the latter attributes, using the settings of the associated reference attributes.

The update function operates on the current element. It should only be used if the Design database has been deleted and rebuilt from macros.

To update cross-database name attributes, on the Update tab, in the General group, click Names.
