Type 2 (Y shaped Revetment.
I started to draw this based on the post-Husky survey plan, however using the dimensions provided the model was starting to give the Colosseum a run for it's money, not to mention the geometry was coming out all wrong, also if all those drawing are meant to be to the same scale, well then there's something wrong there also.
So plan B.
Using Google maps to roughly measure the length and width of the structure in earlier post (which I rounded to the nearest whole number).
I then cut a screen capture of the same image into Illustrator and proceeded to trace out a vector along the centers of the intact wall, I then thickened this line to ascertain the wall thickness (which I worked to be 800mm).
From this I was then able to build a model in SolidWorks:
I then saved the Solidworks drawing back to Illustrator in 1:100 scale so I could test the fit the revetment with several familiar Axis mediums.
