The Join tool allows you to attach a number of objects together
into a single object. The Join tool is almost exactly like
PowerCADD's Attach command, with a few important exceptions. The
objects that are joined together consist of an ordered, end-to-
end group of objects known as a path. Thus, you can combine
lines, polygons, arcs, B-splines, Béziers, and splines to form
an irregular shape that can have a single fill pattern or color
and a single pen pattern, color and dash pattern. (If you join a
line to a Bézier, however, the result is a single Bézier.) Paths
are important for several reasons. First, you can create a
single 'object'-say a maple leaf consisting of lines, arcs,
polygons, Béziers, B-splines and splines-that you can ungroup
and individually edit the objects within the group. Second, when
paths are printed or plotted, they are actually treated as a
single object. This means that a single line dash pattern is
used for the entire object, thus providing an even pattern of
dashes rather than the awk
