# Rebar Material Properties

How to create and manage concrete beam rebar material properties using the Edit Design Properties menu.

Concrete beam rebar material properties are created and managed using the "Edit Design Properties" button on the ribbon bar:

When triggered from the ribbon button, the menu will load in the lower right corner of the Revit UI:

This menu also contains tabs for managing other design properties, including beam design rules and concrete material properties. For more detail on the use of these tabs, refer to [Beam Design Rules](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules.md) and [Concrete Material Properties](/efr-user-manual/calculation-types/working-with-beam-calculations/concrete-beam-calculations25/concrete-material-properties.md).

Rebar material definitions are found on the third tab of the menu:

![](https://4249100372-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgHVzpA9PT0VcuNGp6j39%2Fuploads%2Fgit-blob-646480b42285f9e7dcc17a30f14b331916eba3fd%2Fclip0767.png?alt=media)

In a new project where no previous definition editing has been performed by the users, the menu will be populated automatically with one sample rebar material which is stored in the `.rvt` file by default. Use of this default materials is optional. It may be removed or edited/renamed as desired by the user. Even though it exists in the Revit model, the default material will not influence the behavior of concrete beam calculations unless manually applied to specific beam elements by the user.

Users should note that the basic mechanics are the same for all design definition tabs found in this menu. The processes to "Apply", "Modify", "Add", "Delete", or "Erase from Elements" do not vary from tab to tab. Regardless of which definition tab is being used, users may reference the following sections for guidance about managing design definitions:

[Applying Rules to Elements](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/applying-rules.md)

[Modifying Rules](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/modifying-rules.md)

[Adding Rule Definitions to a Project](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/adding-new-rules.md)

[Deleting Rule Definitions from a Project](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/removing-rules.md)

[Erasing Rule Definitions From Elements](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/erasing-rules-from-elements.md)

[Navigating Rule Definitions](/efr-user-manual/calculation-types/working-with-beam-calculations/beam-design-rules/navigating-rule-definitions.md)

Any attempt to launch a concrete beam calculation when no rebar material has been applied will be halted with a warning:

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/efr-user-manual/calculation-types/working-with-beam-calculations/concrete-beam-calculations25/rebar-material-properties.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
