User Defined Element Types

LEXICON Command Reference Manual

Within AVEVA E3D™ the standard set of elements are often used for a variety of purposes. A UDET allows an element to be created with a more meaningful name, For example an administrator could create clearly defined sub types such as Pipe Lagging, Pipe Painted and Pipe Heated.

The hierarchy of elements which make up a UDET within the LEXICON database is shown below.

UDETWL - (UDET World) is a top-level administrative element. As well as the standard AVEVA E3D™ attributes, this has a DESC attribute which can contain up to 120 characters of text.

A UDETWL may hold UDETGR (UDET Group) elements or individual UDET (UDET definition) elements. A UDETGR has the same attributes as a UDETWL.
