How do I create a new layer from selected features in ArcMap?

Creating a new layer from selected features in ArcMap is a straightforward process. Here's how:

1. Make your selection: In ArcMap, select the features you want in your existing layer using any of the selection tools (e.g., Select Features tool, Select By Attributes, Select By Location).

2. Right-click the layer: In the Table of Contents, right-click on the layer containing the selected features.

3. Navigate to Selection: From the context menu that appears, hover over "Selection".

4. Create Layer from Selected Features: Click "Create Layer from Selected Features". This will create a new layer in your Table of Contents containing only the features you selected. The new layer will appear at the top of your Table of Contents.

In summary, the steps are:

1. Select Features
2. Right-click on Layer
3. Selection -> Create Layer from Selected Features

This new layer is dynamically linked to the original layer. Changes in the selection of the original layer will not be automatically reflected in the new layer. The new layer will maintain only the features that were selected at the time of creation.
