Imports a STEP Physical File into the remote EDMdatabase

...

specified by the given server context. By default the imported data will be stored in a new edmModel. Optionally the imported data may be added to an existing edmModel.

...

The Express schema that defines the structure in the Data Section of the actual STEP file must exist as a dictionary model in the remote EDMdatabase

...

before this function can be successfully executed. The name of this Express schema is found in the attribute FILE_SCHEMA.SCHEMA_IDENTIFIERS in the Header Section of the STEP file

...

.

...

The STEP Physical File format is defined in ISO 10303-21: Clear text encoding of the exchange structures. A STEP Physical File is also referred to as a Part 21 file.

...

The STEP Physical File is an implementation of ISO 10303, and may be used to exchange data between two EDMdatabases

...

or between one EDMdatabase

...

and any ISO 10303-21 conformant application. The STEP Physical File format is suitable for long-term archiving of data.

...

When the option KEEP_STEP_IDENTIFIERS is enabled, a STEP Identifier model is created and connected to the data model created by this operation. The purpose of the STEP Identifiers model is to preserve the relation between the entity instance identifiers used in the STEP file (stepID) and their corresponding instanceIDs in the EDMdatabase

...

.

...

No STEP Identifiers model can be created when the ADD_TO_EXISTING_MODEL option is enabled.

...

The STEP Identifiers model will be opened for read only access when the related edmModel is opened, and the STEP Identifiers model will be deleted when the connecting edmModel is deleted. The STEP Identifiers model can also be handled as an individual model with respect to the EDMdatabase

...

operations.
A STEP Physical File can be created by the edmiRemoteWriteStepFile function.

...

The edmiRemoteReadStepFile operation is very similar to the edmiImportStepFile operation except that edmiRemoteReadStepFile operation take a few more arguments thereby allowing specification of more details.
For information on the format of the file in argument <shortNamesFile>, see Short names in the EDMsupervisor

1	Type	Name	Comment
2	SdaiUnsignedInt	serverContextId	Context identification, from edmiDefineServerContext
3	SdaiString	remoteModelRepositoryName	The name of the edmRepository in the remote EDMdatabase^ that contains or eventually shall contain the edmModel. Repository names are case sensitive.
4	SdaiString	remoteModelName	The name of the edmModel. Model names are case sensitive. If the model exists, the calling EDMuser must have write access to this model.
5	SdaiString	remoteHeaderModelRepositoryName	The name of the edmRepository in the remote EDMdatabase^ that contains or eventually shall contain the header model. Repository names are case sensitive.
6	SdaiString	remoteHeaderModelName	The name of the header model. Model names are case sensitive.
7	SdaiString	stepFile	The name of the file that contains the STEP Physical File to be read by this operation. The default file extension is .stp
8	SdaiString	logFile	The name of an optional file that will contain diagnostic information resulting from parsing the STEP Physical File. If this argument is NULL, the diagnostics will be written to the _ EDMinterface ^_ current output device. The _ EDMinterface ^_ current output device can be defined by the edmiDefineOutputFunction operation.
9	SdaiString	remoteSchemaName	The name of the Express schema that defines the structure of the data in the Data Section of the actual STEP Physical file is found in the attribute FILE_SCHEMA.SCEMA_IDENTIFIERS in the Header Section of the STEP Physical file. This schema will be used as the underlying schema of the new edmModels resulting from this command. Hence this Express schema must exist as a dictionary model in the _ EDMdatabase ^_ when the edmRemoteReadStepFile function is invoked. If the schema already exists within the remote _ EDMdatabase^,_ this argument may be used to overrule the schema name found in the Header Section of the STEP Physical file. Otherwise, this argument should be NULL. To overrule the Express schema name found in the Header Section of the STEP Physical file, specify the name of an Express schema that will be used as the underlying schema of the new edmModel resulting from this function. The name of an Express schema is case insensitive. The specified Express schema must exist as a dictionary model in _EDMdatabase^{_}.EDMdatabase
10	SdaiString	shortNamesFile	The name of the file containing the mapping matrix between the full entity names and their corresponding unique short names. For each STEP AP, a short names file is provided by ISO TC184/SC4.
11	SdaiInteger	options	See list of available options below. Options may be combined by the bitwise OR operator.
12	SdaiInteger	nbWarnings	Variable that will receive the number of warnings resulting from parsing the STEP Physical file.
13	SdaiInteger	nbErrors	Variable that will receive the number of errors resulting from parsing the STEP Physical file.
14	EdmiError	sdaiError	Variable that will receive any _ EDMinterface ^_ error code resulting from the parsing of the data in the STEP Physical file it self. System errors in general will not be returned in this variable.
15	SdaiInvocationId	edmiInvocationId	Currently not used.

Options

...

1	Option	Comment
2	DELETING_EXISTING_MODEL	If the edmModel that is specified by the argument <remoteModelName> already exists it will be deleted and recreated before the STEP Physical file data is imported.
3	NO_STRING_ENCODING	Specifies that the actual STEP Physical file has no encoding of its string data, hence no decoding will take place during the read operation. The ISO 10303-21 specifies that all characters in a STRING data type that have an ASCII value less than 32 or greater than 126 should be encoded in a STEP file and hence decoded when reading the STEP file into an _EDMdatabase^{_}.EDMdatabase
4	DELETE_INSTANCES_WITH_REFS	If an edmModel is implicitly created, this option will disable one of the models built in features, thereby improving its data manipulation performance. This option enables deletion of referenced instances without removing of the references them selves. Use this option with extreme care. Never on models that are meant to remain persistent in the _ EDMdatabase ^_ . This option may lead to inconsistant inconsistent populations containing references to non-existing instances.
5	DELETE_INSTANCE_REFS_ON_DELETE	If an edmModel is implicitly created, this option will disable one of the models built in features, thereby improving its data manipulation performance. This option causes all external references to an instance to be deleted automatically when the instance it self is deleted. Use this option with care. Preferably not on models that are meant to remain persistent in the _ EDMdatabase ^_ .
6	NO_INSTANCE_REFERENCES	If an edmModel is implicitly created, this option will disable one of the models built in features, thereby improving its data manipulation performance. This option prevents the creation and maintenance of "instance references tables". As a result of this, the following operations will not work: The built in function USEDIN, The _ EDMinterface ^_ operations: edmiUsedIn, edmiUsedInBN, and edmiGetInstanceReferences The ExpressX function xpxGetInstanceReferences Use this option with care. Preferably not on models that are meant to remain persistent in the _ EDMdatabase ^_ .
7	UNPACKED_MODEL	No garbage collection for the edmModel when data is freed. The disk space used for the edmModel will normally increase. This option can influence the system performance.
8	USER_CONTROLLED_INVERSE	If an edmModel is implicitly created, this option will disable one of the models built in features, thereby improving its data manipulation performance. This option prevents automatic update and maintenance of the INVERSE attributes in the actual model. Use this option with care. Preferably not on models that are meant to remain persistent in the _ EDMdatabase ^_ .
9	KEEP_STEP_IDENTIFIERS	A STEP Identifier model will be created and connected to the edmModel created by this operation. The STEP Identifier model will preserve the relation between the STEP file entity instances (stepIds) and their corresponding _ EDMdatabase ^_ instanceIds.
10	LOG_TO_STDOUT	Any logged information will be written to the _ EDMinterface ^_ current output device. The _ EDMinterface ^_ current output device can be defined by the edmiDefineOutputFunction operation.
11	ADD_TO_EXISTING_MODEL	The data set in the imported STEP Physical file will be added to the existing population of the edmModel. The data must be based on the same underlying Express Schema as that of the existing edmModel. This option enables incremental population of edmModels from STEP Physical files.
12	CONFORMANCE_CLASS_1	Overrules the mapping method given in the Header Section of the STEP Physical file. The STEP Physical file will be interpreted according to ISO 10303-21:1994/TC1 CC1. The options CONFORMANCE_CLASS_1, CONFORMANCE_CLASS_2, and DIS_VERSION are mutually exclusive.
13	LOG_TO_FILE	Any logged information will be stored in the file specified by the <Log file> argument.
14	HEADER_MODEL_ONLY	Only the Header Section of the specified STEP Physical file will be parsed and imported into a STEP Header Model in the _ EDMdatabase ^{_} . No data model will be created when this option is set.
15	PARSE_ONLY	The specified STEP Physical file will be parsed and checked for syntactical correctness only. No data will be stored in the _EDMdatabase^{_}.EDMdatabase
16	CONFORMANCE_CLASS_2	Overrules the mapping method given in the Header Section of the STEP Physical file. The STEP Physical file will be interpreted according to ISO 10303-21:1994/TC1 CC2. The options CONFORMANCE_CLASS_1, CONFORMANCE_CLASS_2, and DIS_VERSION are mutually exclusive.
17	DIS_VERSION	Overrules the mapping method given in the Header Section of the STEP Physical file. The STEP Physical file will be interpreted according to ISO 10303-21:1994/TC1 DIS. The options CONFORMANCE_CLASS_1, CONFORMANCE_CLASS_2, and DIS_VERSION are mutually exclusive.
18	LOG_ERRORS_AND_WARNINGS_ONLY	Log messages will only be generated for the instances that cause errors or warnings.
19	UTF8_ENCODED_FILE_NAMES	Use UTF-8 for file names
20	UTF_8_STRING_ENCODING	Use UTF-8 for the model
21	ISO_8859_1_STRING_ENCODING	Use ISO_8859_1 for model encoding
22	ONE_FILE_STEP_FILE_PACKAGE	Must be used with STEP_FILE_PACKAGE . Will read one STEP file that contains the model and all the associated data files.
23	STEP_FILE_PACKAGE	Will allow the STEP file to have EDM types FILE and BLOG. Each data file within the model will be available as a separate file.
24	ONLY_USER_DEFINED_ENTITIES	only instances of USER_DEFINED_ENTITY will be populated in the "read step file" operation
25	OPEN_MODEL_FOR_LOCAL_READ_WRITE	Opens the new model for read and write operations
26	EXCLUDE_USER_DEFINED_ENTITIES	instances of USER_DEFINED_ENTITY on the STEP file will not be populated in the "read step file" operation
27	ZIPPED_FILE	Will read a model that is compresses in the .gz format
