This tool, , allows you to draw a headwall in the Main Window.

When you click on this tool, the arrow cursor changes to a pencil. Click the cursor on the point where the headwall is to be inserted, and the headwall symbol will occur.

To enter data, right-click with the mouse pointer on the symbol to open a small menu. Selecting Edit Data
