Families are conveniently grouped together in a tree, which may be filtered by any parameter. Define grouping parameters with '**Configure Grouping**'.

The '**Configure Grouping**' selection consists of the most general parameters. Additionally, the user can use any currently selected parameter within the table to make it a grouping parameter.

The higher the grouping parameter, the higher it will appear in the grouping tree view.

At the bottom of the window, the user can access additional controls for family modifications. Those include:

1. **Export Excel**. Export the current state of the table into an Excel file. The exported Excel file may be used for parameter modification.
2. **Import Excel**. Import all the changed values from Excel to the Family Modification table.
3. **Select Parameters.** Add/remove existing parameters to/from the Family Modification table. Parameters come as a list of all parameters present in the families selected for modification.
4. **Preview 3D DWF**. Opens the 3D DWF of the selected family for previewing if it was created with the library file.

The number of rows shown in the table will depend on the number of Family Types present inside the chosen families.

Parameters can be selected with **'Select Parameters'.**

All parameters from the selected families can be seen on the left side of the dialog. Select the parameters you want to modify by adding them to the right side of the dialog.  Selected parameters

## 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.besmart.software/design-data-management-and-exchange/smart-browser/modify-families/modification-window.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.
