# WS Graphical \[PIG]

**Attack Angle Start:** Starting attack (incidence) angle range for the graphical wind-load definition (unit Angle).

**Attack Angle End:** Ending attack (incidence) angle range for the graphical wind-load definition.

**# of Directions:** Number of attack-angle directions sampled between start and end angles.

**Wind Data:** Table of wind pressures / velocities per direction used to build the graphical load.

**Coordinate System \[Alignment/Global]:** Coordinate system used to interpret the attack angles — Alignment (local PGL-aligned) or Global (project-global axes).

**Is Active \[Yes/No]:** Controls whether this graphical wind-load row is active in analysis.

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.openbrim.org/templates/precast-i-girder-bridge-workflow/loading-pig/loads-pig/wind-load-pig/wind-load-on-structure-pig/ws-graphical-pig.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
