# How To Export Shared Parameters in Revit?

In this article we will demonstrate how to export Shared Parameters and apply them to multiple Revit families in just two steps.

## What are Shared Parameters in Revit?

**Shared Parameters** are parameter definitions that can be used (stored) in multiple Revit families or projects. They are stored in a file independent of any family file or Revit LT projects, which allows you to access the file from different families or projects. The information, defined in a shared parameter container, in one family or project, is not automatically applied to another family or project using the same shared parameter.

For information in a parameter to be used in a tag, it must be defined as a shared parameter. Shared parameters are also useful when you want to create a schedule that displays various family categories (you cannot do this without a shared parameter).

## When to use Shared Parameters in Revit?

- When you want to create a schedule that displays various family categories.
- When you want to reuse parameters. Rather than creating a separate parameter for each element or equipment type, a single shared parameter can be used across multiple elements in a model.
- For automatic annotation updates across a model.

## How to Transfer Shared Parameters to Multiple Revit Families?

To transfer shared parameters from a Revit family or project, you first need to export them. To this, use the **[Kobi Toolkit for Revit](/content/revit/index.html)**.

Kobi Toolkit is a bundle of over 40 different tools that will boost and simplify your workflow in Revit. Under the _Content Admin Kit_ _tab_ _,_ you can find tools for advanced parameters management. In the short video below, we will show you how to use _Parameter Manager_ to export shared parameters and apply them to multiple Revit families with just a few clicks.

In the video example, a Revit Family includes shared parameters we wish to transfer to multiple families. We can do this in two steps.

### Step 1: Export shared parameters

Go to the “Content Admin Kit” tab and select _Parameter Manager_. Select the shared parameters you would like to export into the JSON file. Click on the _Export_ option and define file location. Confirm your choice and _Close_ the _Parameter Manager_ dialog box.

### Step 2: Apply parameters to multiple families

Once you have successfully exported the shared parameters, it’s time to apply them to multiple families.

Select _Update Category_ which is under the Content admin kit tab.

Under _Data_ select the folder in which you have all the families that you want to update and select the JSON file ( _JSON Definition_) you exported earlier. Once done, you will notice that all parameters from the original family have been successfully added to the selected families.

## Conclusion:

By following these two simple steps you can efficiently transfer shared parameters between multiple families in Revit. This not only saves time but also ensures consistency and accuracy in BIM projects.
