# Add Set Window (Freehand)

The Add Set Window (Freehand) option allows you to create a set window by drawing a freehand polygon or "lasso" around a grouping of poles.

Sets created with the Add Set Window (Freehand) option are equivalent in all respects, to sets created with the other set window options (Add Set Window or Add Set Window (Circular)). All of the same rules apply, and the mean plane calculations are exactly the same regardless of the method of window selection.

To use this option:

1. Select Add Set Window (Freehand) from the toolbar or the Sets menu.

2. Click and hold the left mouse button and drag to form a freehand set window which encloses a group.

3. The window will automatically close when the cursor reaches the starting point of the window.

4. You will see the Add Set Window (Freehand) dialog which allows you to choose a Set ID, label and visibility options.

5. Select OK and the mean plane will be calculated for the set and displayed according to the visibility settings.
