Boy are you leaning on a weak reed BH. I don't even know what a vertex is, let alone how to add planks to the platform. But I'm eager to learn so tell me what to do and I'll give it a try.
i think that most cover the whole ship but there must be gaps or holes. looking at the pic it seems that the middle of the ship could use more.
ok from what i see the width is 11.025 per side except for that section that is 13.475. i think these are in meters.
i think they are out of order. so lets try this first.
vertex.0=-11.025,8,-65.844
vertex.1=-13.475,8,-58.187
vertex.2=-11.025,8,68.294
vertex.3=11.025,8,68.294
vertex.4=13.475,8,-58.187
vertex.5=11.025,8,-65.844
that puts them in a counter-clockwise order. i think... negitive is left correct. hummm.
that should fix the holes. what we can do is add 2 more here
vertex.0=-11.025,8,-65.844
vertex.1=-13.475,8,-58.187
vertex.2=-13.475,8,58.187
vertex.3=-11.025,8,68.294
vertex.4=11.025,8,68.294
vertex.5=13.475,8,58.187
vertex.6=13.475,8,-58.187
vertex.7=11.025,8,-65.844
now this might not be the correct pattern of the ship. i'll put it through ACM and get the coords.
but this is a start.
