In Chapter 17, I introduce
blocks
as collections of object geometry that are treated as
single entities in AutoCAD. In that chapter, I also describe giving blocks a little more
oomph by adding
attributes
— changeable text tags that can differ with each insertion.
Other than that kind of slight variation, though, the blocks I describe in Chapter 17 tend
to be pretty static.
