ID Models and ID Separators

An ID model defines the designations for object or design part IDs (identities) and ultimately helps determine which basic information will be registered for the object or design part. Each ID model has a set of primary and secondary ID fields. An object ID model consists of some or all of the 10 primary and 10 secondary identity fields. A design part ID model consists of some or all of the 5 primary and 5 secondary ID fields. When the ID model is connected to a design object or design part class, the unique ID of all objects or design parts in the class share that ID model.

ID separators divide the different sections of the object and design part IDs making them easier to read.

Registering ID Models

ID model can be registered by defining the primary and secondary ID fields manually. An object ID may be defined for Primary 01, 02 and 03 as follows:

Primary 01 Primary 02 Primary 03
Department Type Number

Each ID Model is connected to a class in a separate procedure.

ID Separators

Each class can be connected to an ID separator model, which is used to configure the characters that divide the different ID parts. For example, an ID separator model of '-, -, -' would result in an object ID appearing as 10-PU-001. ID separators are optional, but they make object and design part IDs easier to read.

ID Models, ID Separators, and Changing Class

The following rules apply for ID models and separators when discrepancies caused by class changes occur:

For example, an object in the PUMP MISC class has the ID 10-PU-100-1. The ID model of the class has four display fields with the ID separator character, '-'. The object ID composition is as follows:

Disp1 Sep Disp2 Sep Disp3 Sep Disp4
10 - PU - 100 - 1

If the object's class is changed and the default ID model of the new class contains 3 display fields, the values in the display fields 3 and 4 are combined together into display field 3 by including the existing separator between the two fields. The new object ID composition is as follows:

Disp1 Sep Disp2 Sep Disp3
10 - PU - 100-1

If the new class has 5 ID model display fields, the new object ID composition is as follows:

Disp1 Sep Disp2 Sep Disp3 Sep Disp4 Sep Disp5
10 - PU - 100 - 1 -
