and I would like to select the parallel elements indicated by the arrow, but I cannot… Is there a solution?

these “parallel elements” are called Isocurves - they are used to visualise the surface and are related to the control point density (in this case the option Rebuild with 20 points) and the knots of the surface. Read more about Nurbs Surfaces if you re interested.

you can _extractIsoCurve
or in this case just _arrayPolar a initial line.

what s the next step you re gonna do with those curves ? why do you want to select them ?

Depends on the type of loft. Not sure why you’d need to loft the particular UV isocurves of an already existing surface, unless you were merely using it as a template for recomposing the UV’s etc.

But it looks like your image is already indicating that you have one of the particular UV directions selected of that particular surface, and so selecting both those directions (UV) simultaneously for a ‘loft’, I don’t really think is what ‘lofting’ is.

Maybe, Grasshopper can though. Sounds more like a network loft :sweat_smile:
