Hello,

In 3DEXPERIENCE Cloud, custom attributes can be added to Physical Products using Attribute Management, which stores information on the part definition itself.

However, in some cases, information must be stored at the assembly level, not on the part definition. This is because the same part can be used in multiple assemblies, and the information related to that part can differ depending on the assembly where it is used.

Example:

Part A is used under Assembly 1 and Assembly 2

Under Assembly 1, attribute X = 123

Under Assembly 2, the same attribute X = 456

Since the value of attribute X depends on the assembly context, it cannot be stored on the Physical Product itself. Instead, this information must be stored on the assembly occurrence (instance) of the part.

We noticed that VPMInstance (occurrence) objects do not appear in Attribute Management, and therefore it is not clear how to define or manage attributes at the occurrence level.

What is the correct way to define and manage such assembly-specific (occurrence-level) attributes in 3DEXPERIENCE Cloud?
