Autotagging

Draft’s ‘autotagging’ facility enables you to generate automatically a series of Labels in one or more VIEWS of a Drawing, having defined a set of rules to control those elements that are to be labelled and the (common) appearance of the labels.

The automatically generated labels (which may be GLABs or SLABs) can then be individually edited. For example, it may be necessary to reposition a label or to modify its leader line. The editing functionality is subject to a few constraints so as to prevent Labels from becoming out of line with the criteria under which the autotagging process operated.

The autotagging process is under the control of a Tag Rule (TAGR) element. The relevant part of the Draft database hierarchy is shown overleaf.

A Tag Rule exists as a member of a Layer (LAYE) or of a Tag Ruleset (TRST). Tag Rulesets are owned by Tag Rule Libraries (TRLB).

The Layer element has a Tag Ruleset Reference attribute (TRSF), which if set will refer to a TRST. All automatically generated Labels will be owned by a Layer. Those Labels within a given Layer will have been generated either from TAGRs owned by that Layer or from TAGRs referenced by the Layer via its TRSF attribute.

Having defined a TAGR element, the Labels are generated by giving the command UPDATE TAGGING.

The UPDATE TAGGING command should be given whenever the Design changes such that Labels move (but remain within the VIEW), or if the TAGR itself changes.
