Many thanks Rurudyne,
well.. it does sound easy for you but not simple for me.
Am novice to cad and DS and no teatcher, not easy to move forward!
Unfortunately I do not know how to model a curved surface separately (most probabily starting from a cylinder?!) Definitely mastering math formulas lot of things can be achieved but through this path there is long way to go for me.
Now down to earth, the way I am doing isn’t that much far?!

-After modeling hull including approx. transom side sweep
-Close the deck to get the the top transom curved edge
-from plan view hand adjust aft deck y-axis curve (it could be a regular or ellipse kind of curve)
-From the body plan view I have a full contoured transom which needs now to be closed
-by inserting proper control point values (top aftdeck cl and keel cl points) achieve a matching inclinated cylinder of course on a separate layer, which intersects the hull aft end
The main problem for me is to match the desired transom radius due to the inclination, nevertheless both hand adjusting (compromising) “trial&error” hull to cylinder or cylinder to hull is a tedious job which can easily bring to a mess.
I suppose yr way would avoid lots of hand adjustments and messing around!
If you’re a patient guy and have some more time to spare to try to explain how to model that curved surface separately (without involving too much math) I would very much appreciate.
Anyhow I thank you somuch for yr kind efforts.
Adriano 🙂
