# Wood Beam Calculations

How to launch wood beam calculations and the NDS section types supported by ENERCALC for Revit.

Wood beams share all of the common beam behavior described in the preceding sections.

The primary characteristics that distinguish Wood beam calculations from conventional Steel beam and Steel Composite calculations are:

1.) Specifying the NDS wood material properties of the beam

2.) Specifying the ply quantity of the beam (where applicable)

As with other calculations, Wood beam calculations are launched from the ENERCALC for Revit ribbon tab in the Revit interface.

As with other calculation types, clicking the calculation launch button will trigger a selection process and will await an element pick by the user.

During this process, only beams that are eligible for Wood Beam design will be available for selection. Ineligible elements are denoted with a "not allowed" circle and slit icon on the cursor when mousing over:

Design of wood beams using ENERCALC for Revit supports the use of the following NDS section types, corresponding to the primary default families found in Revit's out-of-box wood structural framing content:

* Dimension Lumber
* Timber
* Glulam - Southern Pine
* Glulam - Western

ENERCALC for Revit does not support the design of LVLs or any other proprietary engineered sections at this time.

## 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/efr-user-manual/calculation-types/working-with-beam-calculations/wood-beam-calculations24.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.
