I just did a quick test in s3d.
I removed the minus sign from the mast and island ("cabina"). I forgot the actual bridge. It swaps to the other side, easy peasy. JUst need to move it forward to the forward elevator. You also need to clone the whole dat.
A good starter project, s3d is actually pretty easy to learn, I'm totally clueless with 3d and I just made a decent start at it
