written a function to bend any section to a given path.
e.g. in below picture
blue line is the section
magenta line is path
cyan line is the section bent as per path
I found this to be quite useful in many cases and if this can be written in
pure openscad could be helpful in sheet bending applications

Hmm. Is the magenta path strictly in the YZ plane?

I think this does what you want in pure, library-free OpenSCAD:

function subdivide_path_y(path, maxy=0.1) =
let(plen = len(path))
[
for (i = [0:1:plen-1])
let(
p1 = path[i],
p2 = path[(i+1)%plen],
steps = max(1,ceil(abs(p2.y-p1.y)/maxy))
)
for(j = [0:1:steps-1])
lerp_vals(p1,p2,j/steps),
];
function dist_index_table(path, i=0, dist=0, out=[]) =
let( lp = len(path) )
i >= lp? out :
i == lp-1? [ each out, [dist,i] ] :
dist_index_table(
path, i+1,
dist + norm(path[i+1]-path[i]),
[each out, [dist,i] ]
);
function fold_to_path(path, poly, maxy=0.1) =
let(
lup = dist_index_table(path),
spoly = subdivide_path_y(poly, maxy)
) [
for (p = spoly)
let(
i = lookup(p.y,lup),
ii = floor(i),
u = i - ii,
pp = lerp_vals(path[ii], path[ii+1], u)

pp + [p.x,0,0]

While the implementation itself uses no libraries, the code used to generate the paths and polygons to replicate your example, is far far easier to write using BOSL2:
include <BOSL2/std.scad>
// Put previously posted implementation code here
path2 = [
[0,0],
each arc(r=3.0, corner=[[0,0], [10,0], [5,10]]),
each arc(r=1.75, corner=[[10,0], [5,10], [10,10]]),
each arc(r=1.75, corner=[[5,10], [10,10], [10,5]]),
each arc(r=1.0, corner=[[10,10], [10,5], [25,5]]),
[25,5],
];
path = apply(rot(90)*xrot(90), path3d(path2));
poly = [
each arc(r=2, corner=[[0,30],[-10,20],[-10,0]]),

color("magenta") stroke(path, width=0.5);
color("blue") stroke(path3d(poly),closed=true, width=0.5);

It doesn't create a texture unless you have a way of triangulating it to
make it into a 3d surface.
