The way I handle this is to make the shape, copy it and then use the copy
to clip the shape. thus giving it half the line weight. These should be
grouped together. when you scale this group, the line will scale but you
can then set the weight to whatever you want by setting the line weight to
2 times what you want, as you now only see half.
