Hi,

  I'm using Sketcher to create the following:

    C=C     C=C
  /      \  /      \
C         C        C

The problem is that I can't figure out how to keep the carbons cis.  I see
the "Add Row" button in Sketcher and I can specify the "Sign."   There are
also spaces to fill in "B/3" F/4" "1/5" "2/6" which I assume assigns
priority.  So how do I actually implement what I want to do?  I've read the
manual, fiddled with settings, and found an old post on a similar subject
but I still cant get my bonds to hold after creating a library.
