About Logical To Physical

The Logical to Physical command synchronizes physical data with logical data.

Important: To create an electrical logical system, ELS - CATIA Systems Logical Electrical Design license is required.

About Logical

The logical data created in the Functional & Logical Design app is used in the Electrical 3D Design to create the electrical geometry and predefined parts.

In the Functional & Logical Design app, the logical structure and physical structure is created.

The logical structure is created under the Logical node in the RFLP tree structure. For more information about creating logical system, see Functional & Logical Design User's Guide: About Electrical Logical Systems.

The logical structure consists of :

Equipment
Connectors
Busbars
Harnesses
Nets (for nets and net groups)
Conductors (for conductors and cables)
Ports (for connector ports and pins).

The part number of the physical component from the catalog is defined in the Predefined Part Number box of the logical component.

Here is an example of an electrical logical system:

To create the 3D representation of the logical components, see Systems 3D Allocation User's Guide: Working with 3D Logical Shapes.

The pathways are created in the Systems 3D Allocation app. For more information about creating pathways, see Systems 3D Allocation User's Guide: Creating Pathways.

The electrical harness created in the electrical logical system is routed through the pathway created in the logical 3D world. The electrical harness is routed through the pathway using the Manual Route command in the Systems 3D Allocation app. For more information, see Systems 3D Allocation User's Guide: Routing Manually.

About Physical

The physical structure is created under the Physical node in the RFLP tree structure.

The physical structure consists of:

Equipment
Harnesses
- Electrical geometry
- Electrical physical system

Here is an example of the physical structure:

The logical components are activated in the Electrical 3D Design app by double-clicking the product under the Physical node in the tree.

About Implement Links

To synchronize logical information with physical information, it is essential to create implement links. They are used to connect elements of different abstraction levels.

The search and creation of implement links is always performed in the context of the first reference-reference implement link found in the hierarchy.

Root Level

During the analysis of logical objects, implement links are by default searched at the root level. Creation of contextual implement links between logical and physical objects depends on the context.

Wiring Context

The following example illustrates the implement links in a wiring context between:

The logical root and the physical root (mandatory before launching the Logical To Physical synchronization)
The logical harnesses and the electrical physical systems

The physical equipment can be placed in the 3D representation of the logical component in the Electrical 3D Design app using the Place Equipment command from the Device section of the action bar. In the Piping & Tubing 3D Design app, you can move the part in the work area by clicking the Piping > Placement methods > Place in space context toolbar. For more information, see Piping & Tubing 3D Design: Placing a Part or a Route in Space.

For more information, see Synchronizing in a Wiring Context.

Cabling Context

The following example illustrates the implement links in a cabling context between:

The logical root and the physical root (mandatory before launching the Logical To Physical synchronization)
The logical sub-system (containing equipment, conductors, cables, etc.) and the electrical physical system
The logical equipment and the physical equipment (not mandatory before the Logical To Physical Synchronize command)

If the predefined numbers are correctly defined in the logical equipment, the corresponding physical elements can be synchronized using the Logical to Physical command. The implement relation is automatically created between the physical and logical equipment when the physical equipment are synchronized.

For more information, see Synchronizing in a Cabling Context.

Intermediate Level

If you organize your product structure by instantiating assemblies, you can create implement links in an intermediate level. As a consequence, analysis of logical objects is not performed at root level but at intermediate level and contextual implement links are created in context of the subassemblies.

The following example illustrates the implement links in an intermediate level between a logical system and a physical system.

During the analysis, theses assemblies are treated as references. During synchronization, contextual implement links are created in the intermediate level context.

Note: The implement link between the Logical root and the Physical root is always mandatary even when synchronizing data in an intermediate level.

Important: Creating reference-reference implement link in an intermediate context is only possible for logical references which are not typed.
