Presentation within the Constructor Modules and ADMIN

The same command line instructions for system types are used when dealing with User Defined Element Types (UDETs), for example:

NEW :MYPUMP

DELETE :MYPUMP

Constructed names will be built up using the UDET for example BOX 1 of :PUMP 2.

UDETs may also be deleted by specifying their base type, for example the command DELETE EQUl would delete either EQUl elements or UDETs based on EQUI.

Normally syntax which navigates the database must use the exact type. However navigation syntax which traverse the database will allow a UDET to be matched against its base-type.

For example EQUl will also climb to a :PUMP based on EQUI. The following syntax is valid for a UDET of type :PUMP, as well as explicit use of :PUMP:

BOX 1 OF EQUl

EQUl

A rule such as RPROP WTHK OF SCTN to work on a FITTING under a UDET based on a SCTN can be allowed. However NEXT EQUl will not identify a UDET of type: PUMP.
