# RC Plate Design Criteria

How to define and assign concrete plate design criteria such as bar cover distances for shell design.

Click **Concrete Design > RC Model Design Criteria > RC Plate Design Criteria** to open the *RC Plate Design Criteria* table.

This table collects design parameters for the concrete plate design process.

You can create as many RC Plate Design Criteria as you need to satisfy the requirements of your design. Once created, you can assign RC Plate Design Criteria to shells graphically.

**Label:** A freeform text descriptor that has meaning to you.

**Edge to Centroid Bottom x Bar:** Distance from the edge to the centroid of the bottom bars oriented parallel to the plate local x axis.

**Edge to Centroid Bottom y Bar:** Distance from the edge to the centroid of the bottom bars oriented parallel to the plate local y axis.

**Edge to Centroid Top x Bar:** Distance from the edge to the centroid of the top bars oriented parallel to the plate local x axis.

**Edge to Centroid Top y Bar:** Distance from the edge to the centroid of the top bars oriented parallel to the plate local y axis.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/design/concrete-design/design-criteria2/plate-design-criteria.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.
