# Local Angle

How to rotate a member about its longitudinal axis using a local angle to reorient sections such as steel girts.

Local angle is a way to rotate a member about its longitudinal axis. It can be useful for situations such as when a wide flange steel member needs to be rotated from its default orientation of web-vertical to an alternate orientation, like web-horizontal when behaving as a girt.

Remember that each member has a local coordinate axis system. The orientation of the local x axis (from starting node to ending node) is particularly important. To visualize the way a positive local angle will affect a particular member, point your right thumb in the direction of the local x axis. The natural curl of your right fingers indicates the direction of rotation of the member when subjected to a positive local angle.

To assign a local angle to a member, select the member and then click **Create (or Modify) > Member Properties > Local Angles**. Either way, the *Element Local Angle* dialog opens. It allows for the specification of an angle to be applied to selected members. (It also can be applied to shells, which is covered in the section on Properties for Shells.)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/e3d-training-manual/building-the-model/properties/properties-for-members/local-angle.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.
