YACHT DESIGN GENERAL QUESTIONS - GEOMETRY

NIck12

Hello to everyone,
I am writing to all of you for ask how to get more clean faces or geometry when I draw yachts, or other kind of ships with sketchup.
When I use some plugins as curviloft, it no work fully to skin and follow geometry.
Then when I do render, shapes, lines, contours it is visiible in some points of yacht design, or when i must intersecate faces, the skin generated is rough, I mean no clean.

Let do an example:
when i draw with follow me, they generate good faces, good skin, but in base to my design, I must change tool for generate faces or skin.

Curviloft and Follow me are very good tools, but I would that when I use it for my desdign I would that skin must be clean, soft.

Ship superstructures geometry when use curviloft no close geometry very well, I can add more geometry as contours, but skin result is not what should be in projetcs.

Please check the examples attached.

So, could you suggest how to reach best result?

To all developers softwares could do a plugins and add calculator tools for NAUTICAL ENEGENEERING SECTORS? As navigation condition hull in sea, center of gravity...So all about NAVAL DESIGN?

Whether there plugins ready, please add here some tips name.

Thank you.

As is shown in picture is too pronounced the line in red zone of the hull. Please check left side hull. About right I know, are segmets.

As is shown in picture the hull bottom is not straight, and red zone hull side , the line is too pronounced. I can add more geometry as well, but the result is the same, or it is visible too lines.

It's hard to tell exactly what the problem is but in general you need to make sure that the transitions between curves or between straight and curved edges are something. That may require adding additional curves to smooth the transition.

Clean and efficient forms typically need good topography. Whilst lofting tools, like CurviLoft, may seen like a good choice there are limits to what you can achieve.

Like DaveCapitalR says...it's hard to decipher the issue. Looks like some of your edges have hardened normals. Keep going though you'll brute force in the end
