In the last several exercises, you learned how to select objects by using both a regular window and a crossing window. Although there are several ways to
make regular and crossing selections (such as when you used the Fence option to trim lines in Chapter 2, “Learning Basic Commands to Get Started”), these remain the two fundamental ways to select multiple objects at once inside AutoCAD. The Select Similar option expands on that concept and adds a way to select multiple objects that have some similarity 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 I06-08-SelectingFixtures.dwg (M06-08-
SelectingFixtures.dwg) is open.
2. Select any line currently drawn on layer 0 that represents a wall
within your cabin (see Figure 6.29)

selecting a single wall line
3. Being careful not to deselect the line on layer 0, right-click and select
the Select Similar option, as shown in Figure 6.29. The Select Similar
command selects all of the lines on layer 0.
4. Use the Quick Properties panel to select the A-WALL layer (see

after using the Select Similar command to select every line on layer 0
5. Save the current drawing as I06-09-SelectSimilar.dwg (M06-09-
SelectSimilar.dwg) by using the Save icon on the Quick Access
