Hi Pilou, the images don't seem to be showing up - looks like you may be using an image host that doesn't allow the images to be embedded in other pages?

Anyway, I think that extracting isoparms would give you what you want - that would be something like actually build the sweep surface and then extract out the curve pieces that you want.

For now probably your line web method of having an additional center rail to make the web through is probably the best way.
