# Build nGraph Function {#openvino_docs_nGraph_DG_build_function}
|
||
|
||
This section illustrates how to construct an nGraph function
|
||
composed of operations from an available opset. Once created,
|
||
it can wrap into a `CNNNetwork`, creating utility for data scientists
|
||
or app developers to define a deep-learning model in a neutral way
|
||
that does not depend on existing Deep Learning (DL) frameworks.
|
||
|
||
Operation Set `opsetX` integrates a list of nGraph pre-compiled operations that work
|
||
for this purpose. In other words, `opsetX` defines a set of operations for building a graph.
|
||
|
||
For a complete list of operation sets supported by Inference Engine, see [Available Operations Sets](../ops/opset.md).
|
||
|
||
To add custom nGraph operations to an existing `CNNNetwork`, see
|
||
the [Add Custom nGraph Operations](../IE_DG/Extensibility_DG/Intro.md) document.
|
||
|
||
Below you can find examples on to how build `ngraph::Function` from the `opset3` operations:
|
||
|
||
@snippet example_ngraph_utils.cpp ngraph:include
|
||
|
||
@snippet example_ngraph_utils.cpp ngraph_utils:simple_function
|
||
|
||
@snippet example_ngraph_utils.cpp ngraph_utils:advanced_function
|
||
|
||
To wrap it into a CNNNetwork, use:
|
||
```cpp
|
||
CNNNetwork net (ng_function);
|
||
```
