Insert using marker, to jack position, creeper will be calculated, based on half span, thickness of hip/ridge and/or valley and position, 0=jack, 1,2,3........the position marker shoud be on the pitching line, can offset for valley creepers, whilst the offset will form a returned valley for hip creepers...........still memory hungry....trying some further ideas.
