I was given the IGES file below which represents one half of a symmetrical yacht
hull. But no matter how I try I cant seem to create a solid out of it... It
doesn't want to be thickened at all, and if I mirror it and stitch it up with a
top and back patch, I get a complete enclosed surface but "Try To Form Solid"
silently fails :-(
Anyone experienced in this area care to give it a try and maybe give me a clue
----------------> Cut here
The entire IGES file was in my post, actually. Very small ;-)
But to my utter astonishment the thickening part of the problem was fixed by
installing ServicePack 3! Still can't do a Surface-Knit to solid, though.
The shape is not flat at the symmetry plane. If you project the edges
into a sketch on the top plane (plane of symmetry), you can see that
there is a little discrepancy at the bow. That means that there are
gaps when you mirror it.
To show this, I trimmed the surface back from the plane of symmetry by
.1 m, mirrored it, and then patched the trimmed out section with a loft.
After this I was able to create the rest of the faces and knit into a
solid and shell. This is not what you are looking for, but it does show
where the problem is.
Anyway, here's a link to my part:
