control points from isocurva

[Aranciameccanica]

Hello.
I looked for other discussions but there is little about modeling through control points.

I got a coffee cup this morning and tried to shape it. the first result is shown in the attached file. the body is obtained with the domando "loft" while the handle with " tubular shape".

I address to you because I would like to realize on the rhino model the light re-entry that is in the real model (image attached)

the idea is to get the isocurva in correspondence of the return that I want to get. turn it into a control curve and then change the control curve.

in general is it possible to transform an isocurva into control points? ?
if I have not been clear I will try to explain myself better... thank you

I try. select the surface, then press the control points button; you will see the surface network with points. At this point you activate the gumball. then select, in the front view, the ring of points corresponding to the point where you want to return, go to the top view and steps by selecting the square of the gumball. Since it does not scale, I believe, in all directions at the same time, first select and press the square in the direction (e.g.) x and by a numerical value and see the result, then select the other square relative to the y axis and do the same. if the point network is not dense enough, use the command "rebuilt curve" and increases the number of points in the u and v directions.

Thank you very much for your help. I did as you suggested and this is the result. Perhaps it was better to increase the control points even more so as to obtain a more fine return.

I think so, if you stick the net, go to influence a smaller area. or, given the simplicity of the shape, maybe you should draw the profile curve by already previewing the recess at the desired height, then make revolution along the vertical axis.

I'm sorry, wasn't it better to do the body of the cup with a superfice of revolution?
draw exactly the profile you want to give to the cup and then rotate the 360-degree section using the superfice of revolution.
Is there any particular reason why you want to use control points?

mariuss, you're right=) for now I'm experimenting so as to find for each command all possible applications. I also saw a video about modeling for control points and so I moved in that direction. . .
Now I'm trying to shape a biscuit door that I attach to youI got a first model through the intersection of two extruded surfaces.Now I'd like to bomb the upper surface a bit through the control points.
the problem is: when I move up the selected control points, the upper surface is separated from the lateral one, despite not selecting the external ones. know how to remedy this problem? ?
Do you have any other modeling proposal?
Thank you.

Do you have any other modeling proposal?
Thank you.

first of all curved in space, when you want a specific form, you will trace curves that define the topology of the object you want to recreate. .

hoping that you can shape a specific form by pulling control points is just lost time.
control points can be used to make small corrections to a surface.

in this case I used curves then surfaces _networksrf and _loft
