5. Next, let's look at the instance parameters. Changes to these param-
eters will update only the selected instance(s). First, select the wall

another, the location line will be maintained. In other words, if you
create an exterior wall and the location line is the inside face, then
when you change the properties or select a thicker wall, it will grow
to the outside—away from the location line.
