That'll be awesome FL2070
If you hit questions shoot them here, and we'll see how far we can go together.
For the issue pictured there, you have tow avenues to explore
- Displace the object in the 3d software so to relocate its center in a way that it fits your shell, and it locates where it should on your cabin
- Use offsets to relocate the object within your aircraft. Right-now it seems to sit on x,y,z = 0,0,0, but you can offset to move it around and find the proper values to get that cockpit to sit where you actually want it.
