Thank you Michael and all. You guys are amazing :o)
I knew it could be done :)
Using Construct / Curve / Project allowed me to generate profiles easily. This is a big step

In the file attached you can follow the creation of the surface I'm looking for by lighting up objects in order.

Now I *only (:o) * need to find an automated way to move, rotate and position the sector profiles along the linear path line.
Is this possible? Any suggestions?
