# Cross-Section
{% hint style="info" %}
**Navigation:** Superstructure > Deck > Cross Section
For detailed parameter explanations, see the [Cross-Section Reference](https://docs.openbrim.org/templates/concrete-u-girder-bridge-workflow/superstructure-cug/deck-cug/cross-section-cug).

## Steps
### Step 1: Understand Cross-Section Requirements
If the section of your deck varies from the beginning to the end of your project, you should define at **least two** cross-sections.
However, in this particular project, the deck sections remain consistent throughout. Thus, it is adequate to define **a single** cross-section to generate this deck.
### Step 2: Navigate to Cross Section
Navigate to **Deck > Cross Section** in the tree view.
### Step 3: Enter Cross-Section Name
Navigate to the first cell in the Name column and enter **CS1** as the name.
### Step 4: Enter Cross-Section Values
Enter all Cross Section values as in the figure.
Quick Tip: Transverse Offset Direction
Offset values use PGL as the reference point.

The Cross Section has been created.

## 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.openbrim.org/examples/concrete-bridge-examples/example-concrete-u-girder-bridge/superstructure-ex1-cug/deck-ex1-cug/cross-section-ex1-cug.md?ask=&goal=
```
`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.
