This trick shows how bricks with plates can be repeated
at regular intervals to align with beams. For example, in
order to have a 5-stud-long space between their pin holes,
two bricks need to be spaced apart by seven plates, by a
brick and four plates, or by two bricks and one plate, as
one brick is three plates tall. Figure 2-17 provides more
examples of studless and studfull pieces in alignment.
