Purlin Rafter Foot Print

Tony sent me a drawing, showing the development of the purlin rafter foot print in plan view, that develops the purlin rafter lines on the draw down roof surface. I haven't drawn the purlin rafter foot print for about a year. So this drawing was just a refresher for the technique used to draw the purlin rafter foot print in plan view. I see the purlin rafter foot print drawn in plan view as more of an artistic type of drawing.

Just a couple of lines in plan view develops the purlin rafter on the draw down roof surface.
