Hi,  
Revolution or Loft mode does not create visible seams.  
Is it possible to create one isocurve or several myself?  
(see screenshot attached)  
Thanks.

May be with the split body tool , then project the edge to the plane what use for the split

i, JST  
Actually, that’s what I tried and i use.  
Project works well for this but the resulting curve is not usable.  
Thanks.

JST,  
I projected a line directly onto the body.  
How to use it as a curve alone. There is no copy and paste 🙂

In my solution you can copy, and got the spline:

Before, I projected the splitted edge:

Then you need a characteristic cross-section. The split body always help…🕶
