Trussed rafter dimension tolerance. Where a camber is specified by a designer, it should
be checked with the trussed rafter lying on its side before being fixed on to the roof
structure. The measurement should be taken as the distance between a string line
fixed between the wall plate support points where rafter meets bottom chord,
and the underside of the nearest node point to mid span.
