The file confuses me some. It starts w. the main wedge. It seems to be close to 45 degrees, but not quite. I can't tell, but I think it is 44.2 +/- .05. That makes every thing hard to line up.
Also, the "measures" are oddly constructed. Seems to be a bunch of thin overlapping rectangles. Polygons w. corner nodes overlapping should allow better placement of object on upper layers.
I have to take care of something else just now, but will try to get back in an hour or so with some solutions.
