Introduction
context
In schematic application an object (equipment, Part, pipe reference) is composed by
- and object Reference that can have a specific type (Logical_Piping_Valve, equipement , ....) and that contains the PLM attributes
- ports that define the interface type & attributes (stored in the Reference
- one or multiple symbol Representation containing the geometrical information of the object and the port positions
When defining the geometrical symbol definition of a Schematic object you can have multiple symbol and for a given symbol you can also define alternate symbols.
About Alternate symbols representation
When defining alternate symbols, all alternate shapes will share at least
- a common geometry base
- same number and position for the Ports
Alternate shapes are typicaly used to manage variant of a symbol
- in case that the difference is not is not directly linked to different type/family of object
- exemple : Valve Open / Valve Close ; Instrument InFeild / instrument InRoom
The alternate symbole shape used in the schema can be driven by object Attributes see video
About Multiple symbol representation
Multiple symbol are usualy use to define symbole shape that are used for different purpose
The Multiple symbol shape used in the schema can also be driven by object Attributes see video in Setup chapter
Warning about Multiple symbol representation
when using multiple symbol Representation, the object is the same, which means that if the symbol is used in 2 different diagrams but using 2 different symbol representations, the Object instance is the same and attributes are common. to be able to modify the attribute , user must have write access on the object (for Reference attributes) and on the Parent (for instance attributes)
customer context:
it is why when working with multi discipline component we will probably define 2 different object references containing each one only one symbol rather than having on reference containing 2 symbols (one per discipline).
This will allows to manage the lifecycle of the 2 diagrams and associated objects in a completly independent way
