WEEK (11)
11.0: Selecting Objects in AutoCAD
11.1: Types of selecting windows
One is a 'crossing window' and the other is a box. If you create the window from right
to left, you make a crossing window. This means that any object that crosses the
border of the window is added to the selection set. This is shown as a dotted line on
the screen. If you create the window from left to right, you create a box. Using this
method you'll add only the items that are completely within the box. This is shown as
a solid line on the screen. The difference is very important.
