Selecting Objects with Selection Windows

AutoCAD has two types of selection windows: the regular selection window and the crossing window. The crossing window is represented by dashed lines, and its interior is, by default, a semitransparent light green color. The regular window is represented by solid lines, and its interior is a semitransparent lavender color when using a white background, and blue when using a black background.
By default, AutoCAD is set up so that whenever no command is running and
the prompt in the command line is Type a command, you can pick objects one at a time or start a regular or crossing window. Rectangular selection windows are created by picking opposite corners of the selection area, whereas the new lasso window selection allows selection windows of any shape to be designated by holding down the left mouse button while moving your mouse around the area to select.
Regardless of the method you choose, when you pick an object, it is selected
and its grips appear. If you select a blank area of the drawing, this starts a selection
window. If you then move the cursor to the right of the point just picked,
you create a regular window. If you move the cursor to the left, you create a
crossing window. You’ll use both crossing and regular selection windows to
select the thresholds and steps:
1. Make sure I06-03-AssigningLayers.dwg (M06-03-AssigningLayers
.dwg) is open.
2. Zoom in to the sliding glass door area. Click the Object Snap button
on the status bar (or press F3) to turn it off, if it isn’t already off.
3. Select the threshold for the sliding glass door by using a crossing
window selection. To do that, follow these steps:
a. Hold the crosshair cursor above and to the right of the upperright
corner of the sliding glass door’s threshold—still inside
the perimeter of the deck—as shown on the top of Figure 6.19

b. Click that point.
c. Move the cursor down and to the left until you have made a tall,
thin crossing window that completely encloses the right edge of
the threshold and is crossed on its left edge by the short, horizontal
connecting lines, as shown on the bottom of Figure 6.19.
d. Click again.
The three lines that make up the threshold are selected.
4. Click the Layer drop-down list to open it, and then click the A-DECKSTRS
layer. The front threshold is now on the A-DECK-STRS layer.
5. Using the Zoom Previous tool, from the Zoom fly-out menu in the
Navigation bar (the ViewCube® on the right-hand side of the drawing
area), enter Z↵P↵, or simply use the scroll wheel to return to a view
of the entire drawing.
6. Zoom in to the threshold at the back door. You will use a regular
selection window to select this threshold.
7. Start a selection window slightly above and to the left of the threshold,
and drag down and to the right, as shown in Figure 6.20. Be sure
to enclose the horizontal threshold lines completely.

8. Move the selected lines to the A-DECK-STRS layer the same way you
did in step 3.
9. Save your drawing as I06-04-SelectingObjects.dwg (M06-04-
SelectingObjects.dwg) by choosing Application menu ➢ Save As ➢
