I am afraid, that will not be enough, as there will be no grid points.

By the way, there is also an "analog" approach. Make a straight print and
use your oven for bending ;-)

Unfortunately, it gives me an intriguing error.
ImportError: No module named inkex

I'll leave such projects for the future, when i'll get a more powerful PC.
The oven approach seems fine for improvisations, but not a finished, hi
quality product.

@ravor - you need to be using inkscape 0.91 - sounds like you have an older
version perhaps 0.48.
There was a change which moved the "units" code from one package to another

• and this raises this kind of error.

I combined the two paths from Dropbox together to generate a closed shape.
Then exported using paths to openSCAD. getting

// Module names are of the form poly_<inkscape-path-id>().
// As a result you can associate a polygon in this OpenSCAD program with the
//  corresponding SVG element in the Inkscape document by looking for
//  the XML element with the attribute id="inkscape-path-id".

// Paths have their own variables so they can be imported and used
//  in polygon(points) structures in other programs.
// The NN_points is the list of all polygon XY vertices.
// There may be an NN_paths variable as well. If it exists then it
//  defines the nested paths. Both must be used in the
//  polygon(points, paths) variant of the command.

profile_scale = 25.4/90; //made in inkscape in mm

// helper functions to determine the X,Y dimensions of the profiles

Of course you'll need to scale it - either in Inkscape (choosing correct
units) first or in OpenSCAD using this code. Helpful function to do just
that is at head. Consult the thingiverse for an example usage.

I think we are converging...without the oven procedure. :)

As a proof of the concept, I coded my proposal of using sweep with a fake
frame profile and arbitray modulation function. And got this:
http://forum.openscad.org/file/n17127/modulation1.png
It spent 68sec to render. A huge gain as I previewed.

The Oskar sweep technique is a little tricky. I used his own variation
called minimum torsion sweep you may find  here
http://forum.openscad.org/Twisty-problem-with-scad-utils-quot-sweep-quot-td9775.html
with a little mod I did for closed paths. A previous version of the mod was
presented  here
http://forum.openscad.org/Minimizing-torsion-sweep-for-closed-paths-tc15813.html
. Those variation and mods intend to reduce unexpected sweep torsions.

Here is the code I have used to generate the above image.

I hope it helps.

"Hi quality", hmm, I wonder, how you will print it. If you use some FDM
printer, you might have a lot of support structure to get rid of.

So.. I have openscad 2014.03, which is the latest one for Linux on their
website.
