# Reusing dimensions with master dimensions

When you are working with an unpublished app, you can create master dimensions so that they can be reused. Users of a published app will have access to the master dimensions, but will not be able to modify them.

You can create a master dimension in different ways.

* [Creating a master dimension from the data model viewer](https://help.qlik.com/en-US/sense/November2025/Subsystems/Hub/Content/Sense_Hub/Dimensions/create-master-dimension-from-data-model-viewer.htm)

* You can also create a master dimension based on a dimension created in a visualization.

  Click Master item> Add new under the dimension in the property panel of a visualization.

  The Create new dimensions dialog opens, with the dimension value from the property panel in Field.

You can also create drill-down groups and cyclic dimensions:
