Electrical Data Exchange Format

To complete the end-to-end process, it is possible to get electrical specifications from external data. These specifications consist of:
  • A device list containing the device attributes and the assembly connectivity
  • And a wire or equipotential list containing their attributes and the from-to connectivity.

This information will be used by CATIA Electrical products to implement in the digital mock-up the electrical systems driven by any electrical authoring tool (schematics or database for example).
You can either access this information through CAA APIs (refer to CAA documentation) or through an XML file. This method (using an XML file) is described in Electrical Integration from External Data.

You will find hereafter the XML schema to create your own interface to CATIA Electrical Tools.

The exchange data model is different from the data model of CATIA Electrical solutions. Actually, this data model consists of pertinent information that needs to transit between Electrical specification tools (schematics, etc.) and CATIA. It only aims at implementing those specifications in the mock-up. So only this pertinent information (objects, attributes and connectivity) is described in the following XML schema and not all the information stored in the CATIA electrical product documents.

In the context of CATIA P1, CAA APIs are not supported.

The following objects are not managed in CATIA P1:

  • Equipotential
  • Connector shell
  • Splice.

even if defined in the XML file: the same XML schema is shared for P1 and P2 products.


  iXF is a format defined by Dassault Systèmes, which is used for the data exchange in XML within CATIA.

Succinctly, iXF is based on the SOAP format and relies on  the XML and the XML schema concept. It makes it possible to describe a grammar (a specific data model) expressing the object, class and behavior concepts as well as documents containing data conforming to the defined grammar.
