A new little tut by Steph about pipes :)
http://tutoriels.steph3d.net/MoI/Tube01/tut.mov

Cool use of the helpers perpendicular :)

And of course you can also modify any circular section (size, position, form)

Does Moi will have a dedicated pipes maker?
For example in the automatic "auto-place mode" perpendicular section don't appear on the path (except extremities)
