# Preferences

## Preference Settings

The preference settings are accessible from the **Preferences** button at the bottom right of the maximized **OpenCutList** window.

## Changing the Interface Language

The interface language of **OpenCutList** is independent of the installed version of SketchUp. You may select among English, French, German, Italian, Russian, Spanish, Portuguese, Czech, Polish, Dutch, Vietnamese or Ukrainian. An experimental version of Arabic and Hebrew is also available (currently without RTL interface). If an **OpenCutList** language matches the language of your SketchUp installation, it will be displayed at the top of the drop down selection. You must close and reopen the **OpenCutList** window for this change to be applied.

{% hint style="info" %}
The **Global Preferences** apply to all future SketchUp sessions, until you change them.
{% endhint %}

## Print Margins

You may select between small and normal print margins. 

## Selecting Length Unit and Precision

By selecting a template in SketchUp, you have already selected a model unit. The model unit can always be changed, but it is good practice to stick with the unit that you are most familiar with and to select an appropriate precision for your work. Check the box if you want **OpenCutList** to display the unit next to each dimension.

These settings change the underlying SketchUp settings from the menu `Model Info -> Units`. If you change those settings, the changes will be reflected in the **Model Preferences**.

{% hint style="success" %}
The dimensions of parts in the **Parts List** and the dimensions of exported parts will only be displayed with units if you checked "Display length unit for each value". Summary values of areas or lengths will always be displayed with units.

The unit used in your model appears at the top of the **Parts List**, next to the file name.
{% endhint %}

{% hint style="warning" %}
Switching units is always possible, but may result in unexpected behavior. 3/4" is 19.05 mm and not 19 mm. **OpenCutList**, just like SketchUp, will have a hard time to deal with "*you know what I mean!*"-type of dimensions.

SketchUp signals approximate dimensions, with regard to your model precision, by prefixing them with a tilde: \~19 mm.
{% endhint %}

## Selecting Weight Unit and Currency

**Reports** require the mass unit and the currency in order to compute weight and cost of materials. Insert a currency symbol of your choice, it can even be a smiley!

![Preferences Tab](https://2764382921-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MUSHuV5bThAGZxy7OHb-1972196547%2Fuploads%2FdRYOgGN7TamuyDSAYwsI%2FInstalling%20-%20Preferences%20-%20Units.png?alt=media\&token=7b8424bb-0578-487b-a87a-c1f6bcb60711)

{% hint style="info" %}
These **Model Preferences** are only valid for the current model. Switching units of length, mass and currency in one model does not affect other models.
{% endhint %}

## Saving to Presets

The **Model Preferences** can be saved as **Presets**. [**Presets** ](https://docs.opencutlist.org/getting-started/installing/presets)are default or **named sets** of settings that can be saved and reloaded at a later time.
