# Supports

How to enter node supports, fixity flags, and enforced displacements in a spreadsheet in ENERCALC 3D.

Tables > Supports prompts you with the following dialog.

![](https://560001759-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FWNe8U6EBBBdUJHdb2X9G%2Fuploads%2Fgit-blob-541c105bf92ce18fc80b7f0a5cc98faae81f6bfa%2FFASTFR~1_img150.png?alt=media)

It allows you to enter supports in a spreadsheet. Each support includes the node ID, the fixity flag, and enforced displacements for all restrained DOFs. The node IDs must be valid (defined).

The fixity flag is a string of 6 characters representing restrained DOFs in Dx, Dy … Doz. For each character in the flag, enter ‘1’ if the DOF is restrained and ‘0’ if unrestrained. For example, “111111” represents a fixed support while “111000” represents a pinned support. Enforced displacements may be applied to the restrained DOFs. They may be regarded as special loads and can be used to model known support settlements. For normal support, they are 0s. Enforced displacements applied to unrestrained DOFs will be discarded.

An empty row is allowed if all rows below it are empty. Selected rows (whole row must be selected) may be cut by clicking the button “Cut Selected Rows”.

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-user-manual/interface/toc175916526/input-data/toc161393904.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.
