Hi Pilou,

> Such fonction don't exist? Maybe must be add to the Array Transform?

No, there's not any function for what you are showing there.

That's basically a 2-rail sweep.

In the future here at some point I'll have an "extract isoparm" command which would make it possible to build a 2-rail sweep surface and then extract some curves from that surface.

That will probably be the way to achieve that in the future.

But I don't believe what you are showing there is related to Angelo's problem though.
