Hi Alastair,

there is wrong survey data in District9:

data dimensions station left right up down

12 1.80 5.10 9.80 1.80

1 10.10 5.10 3.90 0.30

2 23.80 0.00 3.40 1.40

Left and Right of station 1 are 10.10 and 5.10 [m?] so the width of the passage on station 1 is 15.20 m

But in the alien_weaponry the width of passage according of splay shots is on the same place only less than half as on BOBs sketch (district9) and about 1/3 after morphing.

There is another problem with overlapping sketches - see attachment.
