## BuildingBlock class

Represents a glossary document entry such as a Building Block, AutoText or an AutoCorrect entry.
To learn more, visit the [Aspose.Words Document Object Model (DOM)](https://docs.aspose.com/words/python-net/aspose-words-document-object-model/) documentation article.




### Remarks

[BuildingBlock](./) can contain only [Section](../../aspose.words/section/) nodes.

[BuildingBlock](./) can only be a child of [GlossaryDocument](../glossarydocument/).

You can create new building blocks and insert them into a glossary document.
You can modify or delete existing building blocks. You can copy or move building blocks
between documents. You can insert content of a building block into a document.

Corresponds to the **docPart**, **docPartPr** and **docPartBody** elements in OOXML.




**Inheritance:** [BuildingBlock](./) → [CompositeNode](../../aspose.words/compositenode/) → [Node](../../aspose.words/node/)
