About Logical to Physical

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

Before you begin working with the Logical to Physical command, you should be familiar with the concepts described in this section. The following topics are discussed:

License

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

About Logical

The logical data created in the VPM Functional Logical Editor workbench is used in the Electrical Assembly Design to create the electrical geometry and predefined parts.

In the VPM Functional Logical Editor workbench, 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, refer to VPM Functional Logical Editor User's Guide: Electrical Logical Systems.

The logical structure consists of :

  • Equipments
  • Connectors
  • 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 VPM Functional Logical Editor User's Guide: Functional and Logical Definition: Creating 3D Representation for Logical Components.

The pathways are created in the Logical 3D Architecture workbench. For more information about creating pathways, see Logical 3D Architecture User's Guide: Working with Pathways: Creating Pathways.

The electrical harness (here LHarness1) 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 Logical 3D Architecture workbench. For more information, see Logical 3D Architecture User's Guide: Working with Logical Connections: Routing Manually.

About Physical

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

The physical structure consists of:

  • Equipments
  • Harnesses
    • Electrical Geometry
    • Electrical Physical System

Here is an example of the physical structure:

The logical components are activated in the Electrical Assembly Design workbench by double-clicking the product under the Physical node in the specification tree.

For synchronizing the logical information with the physical one, it is essential to create implement links. These implement links are used to connect elements of different abstraction levels. For more information, refer to VPM Functional Logical Editor User's Guide: Implement: Creating Implement Relations.

The implement relations are created between the components shown with arrows.

The physical equipments can be placed in the 3D representation of the logical component in the Electrical Assembly Design workbench using the Place Equipment command in the Device Placement toolbar. You can move the part in the 3D geometry area using the Place in Logical Basic 3D Shape command in the Place Methods toolbar. For more information about placing a part in 3D shape, refer to Electrical Library User's Guide: Using Smart Place: Part Placement Methods.

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