Selecting Objects with the Lasso Tool

---

Use the Lasso tool to make freehand selection of irregular areas.

To select objects using the Lasso tool:

1. Select the Lasso tool .

2. Press the mouse button while the pointer is not over any object.

3. Drag around a portion of a chemical structure or other object.

As you drag, a line appears which defines the Selection area. Bonds, structures, or other objects are selected only if they are entirely within this area. The end points of the Lasso are automatically connected when you release the mouse button.
