+Data Exchange Wrapper (DE_Wrapper)  {#occt_user_guides__de_wrapper}
+============================
+
+@tableofcontents
+
+@section occt_de_wrapper_1 Introduction
+
+This guide explains how to use the **Data Exchange Wrapper** (DE Wrapper).
+It provides basic directions on setup, usage and file creation via DE_Wrapper.
+
+The Data Exchange Wrapper (DE Wrapper) module allows reading and writing supported CAD formats to shape objects or special XDE documents, setting up the transfer process for all CAD files.
+
+It is also possible to add support for new CAD formats by prototyping existing tools.
+
+The DE Wrapper component requires @ref occt_user_guides__xde "XDE" toolkit for operation.
+
+This guide mainly explains how to convert CAD files to Open CASCADE Technology (OCCT) shapes and vice versa.
+This guide principally deals with the following OCCT classes:
+  * The Provider class, which loads CAD files and translates their contents to OCCT shapes or XDE documents, or translates OCCT shapes or XDE documents to CAD entities and then writes those entities to a CAD file.
+  * The Configuration class, which contains all information for the transfer process, such as the units, tolerance, and all internal information for the OCC readers or writers.
+  * The wrapper class, which contains all loaded configuration objects with own CAD format, reads or writes CAD files in the format derived from file extension or contents and saves or loads configuration settings for loaded configuration objects.
+
+@section occt_de_wrapper_2 Supported CAD formats
+
+| CAD format | Extensions | RW support | Thread Safety | Presentation | Package |
+| :--------- | :--------- | :--------- | :----------- | :----------- | :------ |
+| STEP | .stp, .step .stepz | RW | No | BRep, Mesh | STEPCAFControl |

+
+**Note** :
+  * The format names in the first column match the FormatName values used for configuration nodes.
+  * The VendorName for all listed CAD formats is "OCC".
+
+@section occt_de_wrapper_3 DE Session Configuration
+
+Any providers can have their own read/write parameters. The transfer process is set up using DE configuration nodes, which hold all relevant parameters. There are two ways to change the parameter values: directly from code or by an external resource file/string.
+The session is a global or static DE_Wrapper object that stores registered DE configuration nodes and wraps DE commands to work with them. It has some configuration parameters of its own and also keeps track of loaded nodes and specilal global parameters.
+
+@subsection occt_de_wrapper_3_1 Getting a DE session. Code sample
+
+Working with a DE session requires a DE_Wrapper object to be loaded or created first.
+
+Getting the global DE_Wrapping object:
+~~~~{.cpp}
+Handle(DE_Wrapper) aSession = DE_Wrapper::GlobalWrapper();
+~~~~
+Creating a local DE_Wrapper:
+~~~~{.cpp}
+Handle(DE_Wrapper) aSession = new DE_Wrapper();
+~~~~
+It is recommended to create a local one-time copy to work with the session, if no global changes are intended.
+~~~~{.cpp}
+Handle(DE_Wrapper) aOneTimeSession = aSession->Copy();
+~~~~
+@subsection occt_de_wrapper_3_2 Configuration resource
+
+Configuration resource is an external file or string of the following format:
+~~~~{.cpp}
+global.priority.STEP :   OCC DTK
+global.general.length.unit :     1
+provider.STEP.OCC.read.precision.val :   0.0001
+~~~~
+
+@subsubsection occt_de_wrapper_3_2_1 Configuration resource: graph of scopes
+   * **global.** is a scope of global parameters
+     *  **priority.** is a scope of priority to use vendors with their providers.
+     *  **general.** is a scope of global configuration parameter values
+     *  <strong>"..."</strong> is an internal configuration with any internal scopes
+     *  <strong>". : "</strong> is a separator of key-value
+     *  __...__ parameter value, can't contain new line symbols.
+   * **provider.** is a scope of configuration providers
+     *  **STEP.** is a scope of CAD format to configure
+     *  **OCC.** is a scope of a vendor or provider
+     *  <strong>"..."</strong> is an internal configuration with any internal scopes
+     *  <strong>". : "</strong> is a separator of key-value
+     *  <strong>"..."</strong> parameter value, can't contain new line symbols.
+
+@subsubsection occt_de_wrapper_3_2_2 Loading configuration resources. Configuring DE Session
+
+The resource should be loaded after the registration of all providers that should be configured. The resource only impacts registered parameters. To configure a new registered provider it is necessary to load the resource again. Parameters not present in the resource will remain unchanged.
+
+There are two ways to check what parameters are available:
+* C++: Open ConfigureNode file and check the InternalParameter field. Each parameter will be described with a comment. To check the global parameters, use the DE_Wrapper class public methods.
+* Resource: Register all available Nodes to the session, then save the configuration and view all existing parameters.
+
+There are two options for loading a resource: recursive and global parameters only. Recursive is the default option to configure all global parameters (units, priority, enable status) and all registered providers. Non-recursive configures only global parameters and ignores all provider settings. This option is the best for updating provider priority.
