Extending an Object Type / Subtype
Assume that we, in our imaginary application, have a protected cell that needs
additional information compared with an ordinary cell. Instead of doing a complete
new object type Protected Cell Information, the Cell Information object type could
be extended with the additional information for a protected cell.
The following steps creates a subtype of the Cell Information object type and adds
new document aspects, Maintenance and Service Manual, to it.
1. Select the Cell Information Object Type Group, create a new Object Type
object, and name it Protected Cell Information.
2. On the Protected Cell Information Type Definition aspect, select the Type Info
tab. Uncheck the No supertype check box. Press Select and select the Cell
Information object type.
