the swing line is part of the call which is what
has me stumped. the pdf shows 2 doors that are called,
a single and a double, the single and the first leaf of the double
have the swing line, but the second leaf of the double door
does not. the swing line is a sub routine in the script
so may be that is where the issue is.
Any way your suggestion to add the line in the object doing
the calling should work.
