Hi
I try to draw a decanter.
after a shell i do a Move face to increase the thickness of the glass at the base
it's OK.
I would like to change the shape of the inside of the glass foot. I would like it to be curved and not flat. (only the interior not the exterior
Thanks in advance

You should be able to revolve->add
By sketching the shape below in orange, then revolve around the axis shown

Now i would like to create the liquid interior.
How can i duplicate the shell and increase its size to do the volume ?
thanks

Personally I'd just:-

(a) Build a solid cube, starting at the base of the glass, extruded up to the level you want and with a footprint bigger than the glass.

(b) Boolean remove the glass from the cube with "keep tools" selected.  This will give you the fluid inside the glass and an unwanted bit outside.

(c) Delete the unwanted bit.

There are fancier ways but that's pretty universal.

Hope that helps,

Thanks Owen, It's perfect !
I've use Boolean and offset to increase the liquid size.

Nice result, that looks great!. 
I don't think you want that offset though.  If we look at it in cross-section we can see the cognac overlaps with the glass. (Red area.)

Cheers,

Hi,
For Keyshot rendering, liquid part must overlap glass.
Thanks

Ah, now I understand, thanks
Owen.
