Brian, have another count! There might not be 40 but it's getting on that way, certainly more than 18! They are pretty close together.


Edit: never mind, Grendel has sorted it whilst I was posting!

Absolutely brilliant Grendel, I just need to get mine to look the same, maybe in another couple of years of trying {-)

the real trick with 3d is to convert your object in your mind into simple building blocks, the hatch cover on the side is just an elliptic cylinder on its side intersecting with the original cylinder, the flanges- very short cylinders- the bolts hexagonal blocks, then merge all the parts together into one solid lump, if I want a smooth transition between parts I fillet the intersection to give me a radiused 'weld'.
I tend to work in the original units at 1:1, then I can scale the whole thing when finished to any scale I want (scale a copy and you still have the original to scale differently).
