# Alignment Data CADD \[SIG] The Alignment Data CADD refers to drawings that display the defined alignment data. These drawings include information about the vertical curve, superelevation, and horizontal curve within the CAD system. In contrast to other code checks, the drawings are presented in the CAD section. ![image-20250924-152739.png](https://openbrim.atlassian.net/wiki/download/attachments/2394259579/image-20250924-152739.png?api=v2) In the CAD interface, located at the bottom left of the screen, users can select the desired drawing. ![image-20250925-125839.png](https://openbrim.atlassian.net/wiki/download/attachments/2394259579/image-20250925-125839.png?api=v2) ## General **Bridge:** Since OpenBrIM supports the modeling of multiple bridges, this parameter should specify the bridge for which the alignment data will be generated. ![image-20250925-125958.png](https://openbrim.atlassian.net/wiki/download/attachments/2394259579/image-20250925-125958.png?api=v2) ![image-20250925-130047.png](https://openbrim.atlassian.net/wiki/download/attachments/2394259579/image-20250925-130047.png?api=v2) ![image-20250925-130149.png](https://openbrim.atlassian.net/wiki/download/attachments/2394259579/image-20250925-130149.png?api=v2) --- # Agent Instructions: 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: ``` GET https://docs.openbrim.org/templates/steel-i-girder-bridge-workflow/cadd-sig/alignment-data-cadd-sig.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
