Appendix A Object Types Aspects
3BDS011222-510 B 523
An instance can only be of one object type, and an object type can only have one
supertype. But with aspect groups it is possible to inherited aspects from other
sources.
When an aspect group is created it automatically gets an Aspect Group Definition
aspect. It also gets an Aspect Category Definition aspect, which makes it an aspect
category object.
The aspect group categories are visible in the New Aspect dialog (below Aspect
Groups / Aspect Group Reference), and aspects of these categories can be added to
any existing object. All aspects on the aspect group, which are specified as being
‘inheritable’, will then be inherited to the object.
Aspects
Object Type Definition Aspect
An aspect of the Object Type Definition aspect category is required on all object
type objects. It is automatically created when the object type is created, and it is
named based on the name of the type. If the type is called Motor, the definition
aspect will be called Motor Type Definition.
Object Type Reference Aspect
All instances of an object type have an Object Type Reference aspect, which is an
aspect of the aspect category that the object type defines. If the type is called Motor,
then this aspect will be called Motor Type Reference.
The type reference aspect has the same user interface as the type definition, but all
controls are read-only.
If an Object Type Extension Definition aspect exists on the type, the type reference
aspect will show the summary of the main type definition and the extension
definitions.
Super Type Reference Aspect
All subtypes have a Super Type Reference aspect, which is an aspect of the aspect
category that the supertype defines. If the supertype is called Motor, then this aspect
will be called Motor Super Type Reference.
