Using Layers to Organize Your Drawing - AutoCAD 2011 and AutoCAD LT 2011: No Experience Required - page 274

fundamental ways to select multiple objects at once inside AutoCAD. The Select
Similar option introduced in this release expands on that concept and adds a way
to select multiple objects that have some similarity way all at once.
To try out this selection method, you'll select objects whose similarity is that they
are lines on layer 0. That is, all lines currently drawn on layer 0 will be selected.
Although only lines are drawn on layer 0, if you had both arcs and lines on layer 0,
and used the Select Similar command on a line, only the lines would be selected.
Again, because lines are the only objects on layer 0, the Select Similar command is
perfect for this particular application.
1. Make sure 06A-FPLAY4.dwg is open.
2. Select any line currently drawn on layer 0 which represents a wall
within your cabin (Figure 6.28).
3. Be careful not to deselect the line on layer 0, right-click and select
the Select Similar option, as shown in Figure 6.28.

4. The Select Similar command selects all of the lines on layer 0. Use the
Quick Properties panel to select the A-WALL layer (see Figure 6.29).
5. Save the current drawing 06A-FPLAY4.dwg using the Save icon on the
Quick Access toolbar.
