Abstract: A layout marking cut guide lines and drill hole locations on timber members during the construction of a timber structure. The layout tool is a quadrilateral planar body with a portion of one of its sides relieved to form a quadrilateral void. The layout tool has a calibrated linear guide slot and a calibrated arcuate guide slot used to measure and mark cut guide lines on rafters corresponding to various roof pitch angles. The layout tool may also have view holes for marking particular angled cut guide lines and drill holes for measuring the drill centers for foundation bolts on 2.times.4 and 2.times.6 timber members.
