Compound Curvature in Aluminum plate

[fpjeepy05]

Who are you refering to - designers or builders? It's easier and quick to design hull shapes which are not developable than are developable. A good designer will be knowledgeable about the construction methods they design for, both limitations and how to design for efficient construction. If a customer wants something which will significantly impact cost, performance or choice of builders a knowledgable designer might present several alternatives and the tradeoffs between them. For instance if the custome requests a straight, vertical stem and a warped bottom with straight sections the designer should let them know about added costs and any performance tradeoffs might be compared to a design with a curved, raking stem and some curvature in the bottom sections.

Similar for a builder. It usually does not work out well for anybody if a builder takes on a project very far outside of their compotency. A builder frequently can also provide good feedback on how to reduce the cost of potentially improve the quality of a design - for example by saying introducing come curvature in the bottom sections can signficantly reduce the amount of welding and provide a surface with less distortion.

I agree. Also was playing with DevLoft today... It kind of makes it too easy.

Is new member "Bezier Chine Design" the author of the book promoted in the previous text, Dennis Schaffer, who previously joined as "thesecondwind" in 2009?

The "Bezier Chine" method for metal boatbuilding has nothing to do with Bezier curves. It has been previously discussed in several threads:

No, I did not buy the book.

Hi DCockey, Did you look at the website? Are do you want to talk about 10 year old post.
