Create an area in the form of a rectangular bounding box that encloses each object and is aligned vertically and horizontally with the map window.
In the illustration above we have created a bounding box for the province of Zacatecas in Mexico.
Bounding boxes are created as areas and are selected when they are created. We would normally move them to their own layer so that they can be formatted and placed where desired in the layer stack. If we would like to have bounding boxes as lines we can take the areas and use the Boundaries transform toolbar operator to create lines.
The Common Bounding Box transform operator is like Bounding Boxes, but creates one bounding box about all objects in the scope.
In the example above the green areas were created with Bounding Boxes using the lines and the blue area was created with Common Bounding Box.
