# 2.10.5. Map items: split

You can only split polygonal items. For example, you can use this operation to split a single building polygon into sections of various heights if necessary.

To split a building:

1. Click the item on the map.

1. In the attribute panel that opens, click **Edit**![](_assets/btn_03.png).

1. Click **Splitting mode**![](_assets/btn_30.png).

1. Draw the line that you want to split the item along:

    ![](_assets/bld_31.png)

    You can also draw a closed shape. In this case, the cut-out polygon will be located inside the original one and have its characteristics.

1. In the attribute panel, click **Save**.

    The building will be split along the lines you set. The values of the new buildings' attributes will remain the same as they were before you split the original building:
