### 6.3.5 The Automatic Lasso

The automatic lasso is similar to the free lasso. By clicking and dragging you can create freehand curves, by clicking without dragging you can create connections between two points. The main difference is, that the automatic lasso doesn’t create straight lines but a path following the strongest contrast in the mouse area. If you want to select an object, simply click on its edge. From now on a line is following the mouse. If you agree with the suggested path, you only have to click with the mouse.

Sometimes the suggested path may not be appropriate. In this situation you can press and hold the Ctrl-key (Windows) or Command-Key (Mac OS) in order to switch to the "free lasso"-mode. Now you can draw straight connection lines.

Wrong lines can be removed by pressing the Backspace-key.

By double-clicking you end input.

Due to its similarity to the free lasso it has the same settings (see chapter 6.3.4). Additionally a Tolerance is available. Tolerance is the width of the area, in which the best contour is searched for. The Tolerance can be adjusted by using the keys Arrow Up and Arrow Down, too.
