How close is this from being done?

ich glaube allerdings, dass in den letzten 4 Jahren nichts daran gebaut wurde :´(

sieht übertrieben heftig geil aus

Nice job. Keep updating.

Wooooow . Great =)

Truly, truly epic. The size is amazing and your construction style is very nice; to me it speaks to having a strong eye for detail while mixing in elements which are massive and keeping an eye on the bigger picture all the while. The internals look to be very accurate to the Cross Sections and the scale is pretty close to the 'real thing' (~3500m dia I think?). One aspect I am particularly impressed by, and which is sorely overlooked all too often but you got just right, are the structural supports. They are NICE! I would say that they are the best that I've seen but then they are the only ones that I've seen. Still, they put mine to shame >.<. Then there are the power lines, computer core, and reactors. All nicely done and authentic. Fun to explore, and one marvels at the size. It's just sad that it's discontinued at the moment ;(! Hopefully you get back to it some time.

Anyway, very good and thank you for the inspiration that is this Lucrehulk-class Droid Control Ship build.

Oh btw protip for making the flight deck and other floors within the rings... Use the circle brush to make one with diameter of the whole ship and then make another circle, comprised of air i.e. the deletion element, to replace from the centre of the 'floor circle', which has a diameter which matches the inner open ring space. Then just  cut off the surplus so it doesn't cut through the engines and such and copy/paste it into the ship with 'replace air' unticked. It looks like you have this down already but just in case you don't; I noticed that the floor is filled in sporadically.

Epic, I take it this is ~1:1 scale then?
edit: scratch that, dimensions are in the description lol. Super epic thing, I can understand why you'd be taking a break though (that seems to be what you are doing)

epic ship! its amazing! nice size :D good luck

nice spaceship
