I found this starship blueprint on internet:
I would like to start working on it from the warp drive.
I am using the blueprint as background image, but front, back and bottom orthographic view do not match. I will try to explain my problem with an example.
A good starting point to make the warp drive is from a cylinder, using the cursor as point of view. I made it match the blueprint using the bottom view.
Then, since front and view were "broken", I rotated the cylinder again to match the blueprint.
But, as you can see, front and back view are perfect, but bottom view is broken.
I cannot make my cylinder match the blueprint position- and rotation-wise.
How can I solve this problem? Am I misunderstanding the meaning of "front", "back" and "bottom" in Blender?
