Building Object Types

Extend an Object Type / Object Type Extension Definition Aspect
Sometimes it is necessary to be able to develop an object type at different locations.
It could be, for an example, that the subcontractor for the electronic drawings will
deliver the drawings that should be part of the Cell Information object type.
The Object Type Extension Definition aspect makes it possible to add, for example
a Electrical Drawing aspect to the object type Cell Information from an import file
without having to change the Cell Information object type.
To make an extension to an object type in another aspect system than the system
where the object type is defined, make the following steps.
1. Create a new Object Type Group and an Object Type. Name it the same way as
the object type group and object type to extend.
2. Create an Object Type Extension Definition aspect on the object type to extend.
3. Create and configure the aspects the object type extension should have.
4. Select the Aspect Control tab for the Object Type Extension Definition aspect
and configure the treatment of the added aspects, just as we did when creating a
simple object type.
5. Export the aspect that extends the object type and the Object Type Extension
Definition aspect to an afw-file with the Import/Export tool.
6. Open the afw-file on the system where the object type to extend available using
the Import/Export tool. The aspects has to be manually placed on the object
type to be extended.
Composite Object Type Creation
Composite Object Types are used to define more complex typical solutions that
decrease the engineering effort. This section will outline the principles and provide
examples of how to build and use composite object types.
The reasons for building composite object types are:
• The engineering time is decreased due to field proven solution. A composite
object type that is tested and verified does not need the same amount of testing
when it is reused.
