# Modifying Geometries

You can view the properties and features of a Geometry by clicking the **Properties** button:

## Adding and Removing Features&#x20;

In the **Geometry Properties** dialog, you can remove features by selecting the row of the feature, right clicking, and select **Remove Selected Features**:

To add features, use the [**Picks**](/spatialexplorer-8-and-9/user-interface/windows/measurements-window.md) windows to create a geometry. Ensure that the correct geometry is open for editing:

## Editing Geometry Properties

Many geometry formats (SHP, KML, etc) support adding custom fields to features within a geometry. By default, all features created contain a user-modifiable string field "**Description**". You can double click fields to edit them.

You can add or remove custom fields by right clicking the header and selecting **Remove Current Column** or or **Add Column**:

When adding a column or field, specify the name of the column and **Column Type**:

The following generic **Column Types** are available:

| Type Name      | Description           |
| -------------- | --------------------- |
| String         | Text entry            |
| Double         | Decimal number        |
| 32 bit Integer | 32-bit integer number |
| 64 bit Integer | 64-bit integer number |

You can then input values, per feature, for the custom field:

## Saving Geometries

Once a geometry is modified, either by modifying fields or by adding/removing features, the geometry file will be unsaved. This unsaved state is indicated by italicizing and asterisking the name:

<figure><img src="/files/pug9r2SNV33vjV25llf5" alt=""><figcaption></figcaption></figure>

To save the geometry, select it and click the **Save** icon.&#x20;

## Exporting Geometries

Geometries by default are stored as KML, due to KML's flexible structure and ability to accept user-defined fields. You can export geometries to other formats using the [Export](/spatialexplorer-8-and-9/user-interface/toolbars/workflow/export.md) tool.&#x20;

{% hint style="warning" %}
Most geometry types have limitations regarding user-defined fields. KML/KMZ is rather flexible, as it's XML structure allows users to define custom fields with minimal limitations. If you plan on exporting to a different geometry type (e.g. SHP or DXF), ensure that the fields and field names comply with the geometry structure definition. &#x20;
