What's fourth?

I can't understand where I'm wrong? I have to do something that should be simple. . .

the flat surfaces for the faces of the wallpapers I can get them, is the next step I miss. I don't understand what to do the sweep2

Thank you, I had done the search for the fourth, not the fourth, sometimes just a letter. .

for richer: once you make the two flat surfaces you have two possibilities to join each other and make a closed polysurface (solid):
the first is to use the hull itself by cutting it with the two plane surfaces.
then cover the hull and then trim it with the two surfaces holding only the hull slice between the two surfaces.

the second is to sweep two rails between the edges of the two surfaces. The difference between the two methods is that the first is accurate. in the second straight suppose a hull generator that could have a curvature. Of course the mistake is very low because the fourth grade (I learned the ternime) is still respected.

thanks wave, with the system of cuts I understood how to do and finally I can get the bulkheads and everything. Now I have to apply for currents, but I think the procedure is more or less the same. or with the intersection I get the track, I draw the profile and make a sweep. then I cut the bulkheads with the current I get and I have the ready piece to be cut into the machine. I just have a doubt. but so doing the currents sell exactly parallel to the ground while instead they should have a curvature.

depends on how your currents are made:
can be for floors parallel to the water line, or for floors parallel to the cl, or that follow other directions.
the upper face (band) can be flat (usually in the bottom currents) or at a constant distance from the hull (fianchi)
depending on how they are made you follow different techniques of modeling.
I am not a great modeler in rhino, the boats design with solidworks, and sincerely I find it much better, but the principles of modeling are the same, and depend essentially on what one wants to build.
For example, if I do the bottom currents, then wanting to lean the strawberries above, I make them plans. I only need those side by side to give rigidity to the panel, so they have to be at a fixed distance from the hull and then model with an offset of the surface of the hull.
Hi.

I would also like to use solidworks, but I think that for a project in phase completely test it costs perhaps a little too much. with rhino it is believed on the 1200 euros, a completely affordable price.
Just a curiosity. but the result of a sweep1 that crosses a surface, can you cut it with the surface itself? If yes, with what command? I think truncating doesn't work. .

I don't understand the problem. if the surfaces intersect, you can cut. Be careful to try to use single and non-polisuperficial surfaces that in cuts often fail, better make three cuts with single surfaces than a cut with polysuperfici.
I use the commands in English I would tell you _trim or _split.
sometimes with the split (that the same command of the trim but does not throw the cut part) things are better.
Try to tighten tolerance in options and verify that the surfaces are valid in the property tab.
