Annotation Change Rules

Changes to annotation graphics are treated in a simpler manner than changes to design graphics. Annotation Change Rules have an attribute to determine whether they should be applied to Changed Annotations, Added Annotations, or both.

For Changed Annotations, only changes in expanded text strings will be marked. For example, a repositioned GLAB with BTEX '#NAME' that has moved because its referenced design element has moved will not be marked as changed. However, if its BTEX was '#NAME at #POS' then the text string would be marked as changed. The whole expanded text string would be drawn in accordance with the referenced ACSTYL. Associated leader lines, dimension lines, projection lines, or any other graphic elements, would not be marked as changed.

For Added Annotations, all elements associated with the annotation will be marked, that is, the expanded text string and all graphic elements.

The ACRULE attributes, with their defaults, are as follows:

Each CRST therefore only needs to reference one or two ACRULES, one applicable to Changed Annotations, one applicable to Added Annotations. If more than one ACRULE is referenced for a type of changed annotation, only the first, in database order, will be applied.

The syntax for the Annotation Change Rule Application attribute is:
