Space Ship building pack??????????

I’ve seen people build some cool ships on such as this
but the Adv dupe wont work because im missing something and i have no idea where to get it!
I want to make my own ship, It says in that link that i need the latest spacebuild svn?? ive also heard of Sbep whatever that is lol
Can someone give me a link to some space build addons?

Thanks :slight_smile:
That second link was perfect
