Not long at all to make the generic shuttlebay and cut ports for it, but since the bridge is actually a combination of 3 seperate 3D rips, it took an eternity aligning and merging them, and ensuring there were no double vertices/faces. (For everyone wondering why nobody ‘rips the entire map’, yes you Civil, this is why.) It took several hours alone to manually smooth the more elaborate areas of the exterior after I discovered how useless autosmooth was for this.
The faceplate of the bridge (picture #2 of the original post) is still to scale which provides a key. Compare it to this picture of the original. The bridge’s faceplate protrudes from the same section.
If your mainly interested in it’s relation to the hammer grid, here is my version, sitting in flatgrass, next to a full scale version someone made a while back.=P (which comes from the ‘IAC’ (In Amber Clad) pack, but has no useful textures, interior or physics model)
Its still ridiculously large, but definitely capable of maneuvering around most maps.
