I tried to make a truss with a warren configuration, it is made as a 'structural truss family'.
The diagonals are always spanning 3 meters, I made one array for the diagonal going up, one for the diagonal going down.
The flexing in width is without a problem (if you keep the parameter for the array above 1).

Flexing in height is a different story, as soon as you put a diagonal in an array it loses its connection with the bottom chord.

However, Revit has a 'Howe flat truss' which does exactly that, flexing in width ánd flexing in height although it is an array.
Does anyone know how they built that family, I can't see any constraints within the array.
