Well we are getting off track here.
The example was one Serge made up to test worst case,
not intending to actually design or build it.
Keith and I were having a bit of fun with trying to make
the roof actually work.
That aside, Serge was trying to see if one could pick a
closed lwpolyline and have a routine draw the roof
skeleton 2D in plan view. Provided all roof sections are
hips, same pitch and at the same plate height.
It appears to be a difficult task.
Any ideas?
