Ship Hull by Curviloft

Hi Charly. Do not know if I have better ideas, just want to confirm that su+ curviloft and bezierline are good for designing boats (or ships). Love your experiments with the rings. -Teo[attachment=2:2yk4n3il]<!-- ia2 -->Sketchup klipp båt copy.jpg<!-- ia2 -->[/attachment:2yk4n3il][attachment=1:2yk4n3il]<!-- ia1 -->Sketchup klipp båt2.jpg<!-- ia1 -->[/attachment:2yk4n3il][attachment=0:2yk4n3il]<!-- ia0 -->Sketchup klipp båt3.jpg<!-- ia0 -->[/attachment:2yk4n3il]
Btw I have borrowed some (in the first image you see it) from van dam woodboats website (it´s the 26´ Hacker- craft) and the rest I make it like I want it. Just for fun. I\m not gona build this boat. But you need very little information to make a pretty good copy of something like that if you find some info on the lines in 2 projections. I´d say they give away too much info here.

This stuff is cool. Now someone needs to come up with a plugin to do all the hyrdodynamic calclulations.

Yes, that would be nice!

I imagine that as difficult and impossible to realize that in Sketchup. If you require hydrodynamic calculations, I recommend the specialized program Delftship free.

I was thinking of Delftship and Hulls (also free) when I made that comment. But someone who understands the math and can write the ruby script could probably write a plugin to do it in SketchUp. When it comes down to it, though. One would probably be better off designing boats that are to be built in an application designed for that.

This discussion reminds me the old times of my first Sketchup experiences when I had only the @last bezier.rb script and the Sandbox tools.

Very nice work there, Fredo6.
I've always admired that. -
Jeff, as I mentioned, I think those programs are better for real hull design. I've done the same sort of steps as you outline and I've also imported the DXF file from Hulls directly to SU and worked with that.

Using Curviloft is pretty cool. But frankly, I find using Delftship: http://www.delftship.net/ and Carlson's Hull Design for hard chine hulls: http://www.carlsondesign.com/ programs quicker and they have the advantage to doing the requisite hydrostatic calculations too. Both have been mentioned, I think, in another thread and both are free. Understandably, this means learning at least one other program and you lose the "intergrated" SU-only solution. You gets some, you gives some...
By way of example: currently I'm using Carlson's program to work out a "stitch n glue" design for a turn of the century Mississippi river skiff, which is a hard chine hull form. Once the design is finished in Hull Designer, I save the resulting .hul file, import it into Delftship and then export it from there as an .obj. Import it into SU using the .obj import plugin and there you go! So far, I haven't had any problems getting the Delftship .obj files imported, even when I tested some fairly complex hulls.
I don't mean to detract from using Curviloft, but if one needs the hydrostatic information, I'm simply suggesting an alternative method.
Cheers.

Ah, Dave, so you did ...
