The mapping file that accompanies the installer contains the mappings between DEXPI classes and Autodesk® AutoCAD® classes for the ISO-10628 configuration. If you prefer to use a different configuration, you must create new ClassMappings for the classes in your target Autodesk® AutoCAD® Plant 3D™ configuration and create corresponding PropertyMappings.

SymbolRegistrationNumber is required if you have multiple different P&ID classes mapped to the same DEXPI class. The number is used during the import process to determine which one ClassMap to use. If a class contains SymbolRegistrationNumber, it will have SymbolRegistrationNumberAssignmentClass Generic Attribute after the exporting. During the import, an appropriate class mapping will be searched for by the SymbolRegistrationNumberAssignmentClass value. The example below shows ACAD classes mapped to the same DEXPI class but with different SymbolRegistrationNumber.

PropertyMap element is used to map a P&ID class property to a specific DEXPI Generic Attribute.  It contains the next attributes:

• ACAD_Property is used to specify a P&ID class property.
• DEXPI_Attribute is used to specify DEXPI Generic Attribute.
• DEXPI_Attribute_Value is used when the user wants to export an attribute with some default value, instead of the AutoCAD asset database value.
• Format is used to specify what value type the attribute value will have (e.g., double, string).
• Units are used to specify what unit type the attribute value will have.
• DEXPI_Attribute_URI is an RDL reference for an attribute.

To install or reinstall the DEXPI Interface, run the DEXPI.AutoCAD.PID.msi file and follow the instructions.

DEXPI Interface for AutoCAD Plant installation directories: 

Location of files required for the configuration:

There are five main AutoCAD commands in the DEXPI interface:

• DEXPI_EXPORT – used to export P&ID drawings.
• DEXPI_IMPORT – used to import DEXPI XML files.
• DEXPI_MAPPING_EDITOR – used to edit an existing mapping file (e.g., existing classes, property mappings)_.
• DEXPI_VALIDATE_XML_FILE – validates selected .XML file according to the current Proteus XML Schema.
• DEXPI_INITALIZE_ROUNDTRIP_PROJECT – Creates a new drawing in a new project for the roundtrip. The new project will have the same classes as the original project.

INITIAL TOOL SETUP

The mapping file that accompanies the installer contains the mappings between DEXPI classes and AutoCAD classes for the ISO-10628 configuration. If you prefer to use a different configuration, you must create new ClassMappings for the classes in your target AutoCAD Plant configuration and create corresponding PropertyMappings.

MAPPINGS AND SETTINGS

A settings file is used to configure both the export and the import processes of the DEXPI Interface. You shouldn't delete any of the setting options for the proper work of the plugin.

The mapping file is used to map AutoCAD P&ID classes to DEXPI classes and vice versa. A main structural element of the mapping file is ClassMap.

ACAD_Class is used to specify a P&ID class we want to map.

The list of known components that cannot be exported due to technical limitations or limitations in the DEXPI specifications:

• Non-associated Hatch
• Nozzles as EndLine components without any relation to the Equipment (e.g. Spray Nozzle)
• Line Gap
• Equipment AttachmentPoints
• Equipment-Motor linking
