Name
In AVEVA E3D™ any element may be given a name. The name always starts with a '/'. At the user level, it is this name that is typically used to identify an element. Names may of course be changed, thus there is no guarantee that the element named '/FRED' today is the same as the element named '/FRED' yesterday.
An element need not have a name. For these elements AVEVA E3D™ creates a constructed name, consisting of the relative position in the hierarchy up to the first named element.
e.g. BOX 2 OF SUBEQUIPMENT 1 OF /VESS1
Whilst the constructed name can be used to identify elements, its use is even more volatile than named elements, since the order of an element in a member's list may change.
You can duplicate the name of an element in a Design (DESI), Production (MANU), Schematic (SCHE) or Engineering (ENGI) databases in the current MDB. For example an element can be named `/FRED´ in the DESI database and a different element can be named ´/FRED´ in the MANU database.
AVEVA E3D™ is case sensitive and AVEVA recommends you stick to UPPERCASE characters. If you create an element named /FRED and at some later time you try to find it by typing /fred or /FreD, it will not be found.
