The rule group UpdateTemplateInstances controls the maintenance of features that have been created using templates.
The Template feature rules are system rules, and must never be disabled or enabled manually.
When you create a template, you have the option to group features. Then, when you move or rotate a feature of the group, AutoCAD Map 3D treats the group as a unit and moves or rotates all other features the same way. The feature rule Update Template Instances controls this behavior for the feature classes that are part of the template.
