Properties of a sketcher for lofting..?
Properties of a sketcher for lofting..?
(OP)
Hi I'm trying to make a 3D geometry of a gulf for meshing purposes; I'd like to loft it bottom->top and I did the profiles but "loft" won't select them. They're all closed curves in different sketchers and different planes, containing only the visible geometry. What might be the problem? Thax a lot!

My suggestion would be for you to extract and explode the P-lines, and then make splines (from points) at the line intersections. When you have smooth geometry, you'll have a much better idea of what you challenges are going to be. (or maybe you'll get what you want with no trouble)

* for you.
I'll disagree on one point. Splines aren't the best choice because they have reversals.
What he should do, IMO, is fit in conic sections.

Thanks for the star. I feel honored to receive one from you.

1. the geometry of the gulf was re-created by SMS (triangulated) and the points (just points, not the geometry) were exported into a .dxf file;
2. the .dxf file was exported to .igs via mechanical desktop
3. the .igs was dumped into I-DEAS and made into a domain by Fit Surface to Points and extrude options;
3. I-deas file was exported into .igs, imported into Catia and made into a solid (I-deas won't swollow making a solid out of such a complex geometry; the surface was fitted to over 56 000 points).
4. Catia file was modified into the desired domain, .igs-ed, and returned to I-DEAS
5. meshing was executed in ideas by partitioning the domain as you would for mapped meshing, which you can't do because of the complexity of the geometry. Use "sweep mesh" instead (you'll find it under options->menus->generate)...
6. Export to unv and FINALLY: FLUENT....
