    In writing my overly long and digressive post yesterday - the one
    about  the log house whose windows didn't match - (What's that got
    to do with  ganoksin?)  - I did increase my understanding of how the
    various  problems came to be.  

    Why didn't the windows on each side of the house match?   Because
    all  those drawings were on separate sheets of paper, not adjacent
    on one  sheet where the mismatch would be obvious. 

    Why were the windows unable to open? The roof structure and the
    walls  were likewise almost certainly on separate sheets - each
    sheet perfectly  rational on its own, but not shown was how it
    related to other parts of  the plan.  You could draw a fine plan of
    a wall but without drawing in  the roof on the same drawing you'd
    never see how its structure  interfered with the windows. 

    So the writing-out of the whole adventure gave me a little boost in 
    understanding of a particular sort of design screw-up and how it
    came to  be built into the house before anyone saw it coming. 

    Oh yeah, also the foreman at the sash shop was an eejit whose brain
    was  AWOL and I hope he never got paid. 

    So what I said at the beginning of that post , sort of intuitively, 
    needs to be made explicit. Draw or build a plan/model with all the
    parts  in place, showing how they relate. Separate drawings of all
    the parts  just won't do. 

Thanks for letting me rattle on.
Marty in Victoria - another sunny day, oh sigh!
