When assigning existing objects in the drawing to new layers, your strategy will be to begin by selecting several of the objects that belong on the same layer and that are easiest to select. You’ll reassign them to their new layer by using the Layer drop-down list. You’ll then move to a set of objects that belong on a different layer or that belong on the same layer as the previously selected object but are slightly more difficult to select, and so on.
1. If it’s not open already, open I06-02-AssigningLinetypes.dwg (M06-02-
AssigningLinetypes.dwg) by clicking the Open button on the Quick
Access toolbar. Verify that the A-WALL layer is set as current as outlined
in the “Using the Current Layer as a Drawing Tool” section earlier.
2. In the drawing, specify a selection window down and to the left to
use a crossing selection window (a green box with dashed lines) that
selects the front deck, as shown at the top of Figure 6.17
F igu re 6 . 1 7 : Selecting the front deck (top), deselecting the front stairs (middle), and the
completed selection (bottom)
Grips appear, and the lines glow blue, signaling that the objects
have been selected.
3. Hold down the Shift key, and select the front stairs with a crossing
selection, as shown in the middle image in Figure 6.17. The stair lines
appear solid again.
Selecting objects with the Shift key pressed causes objects that are
already selected to become unselected (removed from the selection
set), while there is no effect on unselected objects.
4. Repeat the process on the rear deck so that the deck is selected but
the back stairs are not. The selected components should look like the
bottom image in Figure 6.17.
Notice also that, in the Layer drop-down list, the layer being displayed
now is layer 0 rather than A-WALL, the current layer. When
objects are selected with no command running, the Layer drop-down
list displays the layer to which the selected objects are currently
assigned. If selected objects are on more than one layer, the Layer
drop-down list is blank.
5. Click the Layer drop-down list to open it (see Figure 6.18).

6. Click the A-DECK layer. The list closes. The A-DECK layer appears
in the Layer drop-down list. The deck lines have been moved to the
A-DECK layer and are now green.
7. Press Esc to deselect the lines and remove the grips. The current
layer, A-WALL, returns to the Layer drop-down list.
