I have not posted anything much lately as “Windows Live Writer” as stopped working with the new security requirement of Google Blogger. So this is my first attempt at posting using “Open Live Writer”
I have been modelling a 2.5km road corridor lately with superelevation and a central island with turn bays. In order to model the turn bays correctly with the right crossfall and also the median islands I came across this video on youtube which was very helpful.
In my situation I also had a number of intersections that I modelled first in the corridor and then had to swap the primary through assemblies to assemblies that included the median island and set the appropriate targets for the island offset assemblies.
