I just stumbled across this one. Say you have cee purlins every 4', and the roof is sloping 3/8" per foot. You can insert the first purlin, then set the roll angle. Then, in plan view, use the offset command to offset the purlins every 4'. Here's the cool part: the purlins will follow the roll angle when being offset. So they are already going up from purlin to purlin at 3/8" per foot. Pretty cool.
