# Shell Properties

How to define material, thickness, and local angle and assign them to selected shells in one step.

We have already seen how to define Material, Thickness, and Local Angle and how to assign each of these to a shell. But sometimes it may be easier to define the necessary properties and then assign all of them to one or more shells all at once. This is where the **Create (or Modify) > Shell Properties > Shell Properties** command can be very useful. It opens the *Shell Properties* dialog, which allows you to select desired shells and then assign Material, Thickness, and Local Angle to the selected shells all in one step.

## 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-shells/shell-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.
