# Access Hole Design \[CBG] The Access Hole Design section provides library objects for modeling access-hole cutouts in the bottom flange of a steel girder. The model object defines the plate geometry, cutouts, mesh, and edge boundary conditions; the load object applies edge forces and moments to an existing access-hole plate. For a detailed explanation of each library object, refer to the relevant section of the documentation. --- # 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/concrete-box-girder-bridge-workflow/access-hole-design-cbg.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.
