thanx for elaborating andrespalma
with loop slice tool (alt+c) you can slice only selected polygons and not only In the middle, but you can decide the number of slices it does, if they’re uniform or free, place em where you want.
as for following the curve the shape would have once subdivided you don’t have that, basically because subpatches aren’t nurbs and an edgeloop is not like an isoparm unfortunately. what you’re actually cutting is a loop of polygons 8you can see this activating the cage when working in subpatch or toggling from subpatch to polygons and vice versa)
instead , when slicing in Modo you can set depth amount (which is kinda an innovation compared to lightwave 3d bandsaw tool) so that ou can get something similar to what you ask for, but not the same.
it surely would be nifty to have such a feature tho.
