# Model Editor This section details the concepts of building the node structure, editing the nodes, and making changes to the model. To go to the Model Tab, click **Model** on the top left corner of the visual.

This opens the model in the form of a grid where the nodes are listed in the model hierarchy along with their node properties. Find below the image of a custom model where the node structure can be customized and edited manually.

Within this view, there are various editing options provided at the node level and the model level. They are explained in the sections [Node Operations](/model/model-editor/node-operations.md) and [Editor Features](/model/model-editor/editor-features.md). Let us start with the modeling features that are available with respect to nodes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
