# Edit Part

To edit the properties of a **Part**, click on the pencil symbol in the **Parts List**. If you select a single **Part**, the **Part Properties** Window will open, allowing you to edit a single part or a group of identical parts.

If a down arrow is the first icon after the description, multiple **Parts** are grouped together, because the **Options** setting [**Group Similar Parts**](/features/parts/options.md#general-tab) is enabled. In that case, you will only be able to edit their common attributes. Click on the arrow to unfold the group and select each **Part** individually.

If you selected a group of **Parts** spread over several lines, only their common attributes can be changed.

## Part Properties

The Part Properties window contains five tabs:

* [General](#general)
* [Material Specific Tab](#material) (Dimensional, Sheet Goods, ...)
* [Axes](#axes)
* [Oversizes](#oversizes)
* [Info](#info)

{% hint style="warning" %}
Some tabs will only appear if a material has be assigned to the part.
{% endhint %}

{% hint style="success" %}
**OpenCutList** can highlight the part in your model.
{% endhint %}

### General

Within this tab, you may change the Name and Description of the component, associate it with a Material, and add or remove Tags.

### Material Specific Tab

Depending on the type of material of the part, this tab will display the configuration options.

### Axes

**OpenCutList** shows you how it interprets the local SketchUp axis (length is <mark style="color:red;">red</mark>, width is <mark style="color:green;">green</mark> and <mark style="color:blue;">blue</mark> is thickness) of the Part. You may reorder the dimensions. At the same time, you may ask **OpenCutList** to change the location of the axes origin and to lock the orientation (in case you have selected Automatic orientation in the [**Options**](/features/parts/options.md#general-tab)).

{% hint style="success" %}
All axes operations are actual SketchUp operations, so they directly affect the local axes of your component.
{% endhint %}

{% hint style="info" %}
When drawing your components, you may ignore the axes and then set them here.
{% endhint %}

If a part has been flipped along one of its axis with respect to the component definition, an icon will  indicate that this part is **mirrored**.

### Oversizes

The dimensions of your components are usually finished dimensions.  A length and width oversize, and even a thickness oversize for solid wood, can be applied to all parts via the **Material** configuration. Note, however, that there are situations where one would like to make a single part slightly larger because it will be adjusted when the part will be installed (filler strip, cover panel, ...).

### Info

Instances of components in SketchUp with the same thickness and the same material become parts in **OpenCutList**.

When creating a component with *Make Component...*, you may:

* give the component definition a **name** by replacing the default text (usually *Component#1*), or leave the default identification.
* set the component axes or rely on the default Sketchup behavior, which sets the component axes parallel to the model axes. The global option of the extension, **Automatic orientation of parts**, will then interpret the 3 dimensions of a part such that the largest dimension is **length** and the smallest dimension is **thickness**, the third dimension becoming **width**.

It is important to correctly set the component axes to convey the desired grain direction to **OpenCutList**. With the default Sketchup behaviour, you may get unexpected results, as in the case of a short but wide part.

These parameters may be changed at a later time, but **OpenCutList** will use them to describe the part in the Parts List and to retrieve its dimensions.

## Description

A component may be reused several times in a model, therefore you can label the **instance**. This label will also appear in the Parts List.

## The Bounding Box

Every component has an enclosing bounding box defined by the extent of the object along the component axes.

The **length** of this box is represented along the **red** axis, the **width** along the **green** and the **thickness** along the **blue** axis. If the components axes are set incorrectly, this may lead to a wrong interpretation of the dimensions of the component.

If you are not familiar with the concept of bounding box, checkout this video [SketchUp Skill Builder: Group axis and bounding box](https://www.youtube.com/watch?v=2UnzHwAt7mc).

## Working with Scaled Components

**OpenCutList** also takes into account scaling of components. Although the description of the parts will be the same, they will appear on different lines of the Parts List.
