I am trying to reproduce the superstructure here. The sides are generally lines. However the top has kinks at the stern. IN order for the plating to be smooth, the vertical profiles cannot be straight at the kinks.
When you are building a model ship 3d, air, car and so on. it is essential to carefully choose the documents to be used as a reference. In this case, I would start from the main sights. This would say that would be fine:
(quickly found on Google images) I would say that there are already 90% of the information you need. Only then you can use the photos (keeping in mind that the photos have distortions due to perspective).
If volglio save hours of modeling, it invests a lot of time in the documentation.
My 2 cents
Here is one I made in a different project where I had the same problem (with only one kink).
The green and black to the right of the green are the cop edge and the red is the bottom edge. The 10 blue curves at the right are lines. The 12 blues at the left are non-linear curves. I extended the surface up and down then I tediously adjusted the curves until they produced a smooth surface.
I was trying to find a simpler way of determining the curvature.
Because of my bad english I find it hard to explain.
I hope the help file.
use of a degree curves 5 and 7 control points for the surface.
activating the history of construction and then sweep 1. act on the curves of the control point and the surface will change accordingly. Use ONLY the original curves as a reference.
The file I enter here does not correspond to the real model, in particular in the conjunction point of the island to the hull. use the handles to get the desired result. Problem Plating.3dm (13.1 MB)
