problem with swept

Bye to all,
I attach a .prt file and an image of a drawing made with acad to show what I would like to get.
My swept is slipped behind, so I can't make a mirror, as I'm modeling a quarter of my piece.
How do I keep the upper and rear flat surfaces?
Moreover, as you can notice, the surface is not beautiful.
is it possible to convert the sketches of the guide curves into spline and keep them as reference curves, so that the change, the spline created is updated?

Hi.

in the jpg file is represented the swept dialog box.
you can select section curves (max 256) and guide curves (max 3).
the latter define 'the degrees of freedom' of the swept: if you select only one guide you must also define the orientation and scale, if you select two guides disappear the orientation method section, with three also disappear the scaling method.
alignment, however, has another meaning and defines how u and v are distributed in the surface.

to shorten it in your case I would also define a third guide (see attached file).
the speech on the surfaces is still very vast.
I also put another 'deviation' image in which I mirrored the solid and analyzed the deviation between the two surfaces. As you see, they're not tangents, so if I had to make a mold with this math, you'd find yourself a nice line.

for the aesthetic appearance of the surface (and a swept hardly gives you a 'nice' surface), use the splines is necessary. in the file that I send you I 'transformed' the spline sketch with a join curve, and as you see it does not change a great deal. the reason is very simple: to make a good spline you must/you can lean on a sketch and build the curve by defining the required continuity g0, g1 ... and analyzing the 'pettine' of the same, trying to make it as simple as possible (less possible points).
only with 'beautiful' support curves can make beautiful surfaces.


I hope I helped you.

Thank you. .I didn't think I needed a third guide curve, I thought a thorn or option would make the object already correct.
to remove the line, I will try to make half a piece instead of a quarter.
Thank you again.
