Creating curve design

Question

Hi, in the image below you can see point "3" is the bottle that I created using blender 2.69. "1" is the side view of the original bottle "2" is the front view of the bottle. Now I want this design of the curve on my blender bottle, but I have no guess how to achieve it. I mean how to create those design on the bottle. The curves on bottle are like small gutter which are towards inside of the bottle.

Are the knife tool (K shortcut) and bevel (Ctrl B shortcut) available in edit mode in 2.69? — lemon, Mar 15 '17 at 06:16
Yes these options are available, but how can these create curves? — Prashant Tomar, Mar 15 '17 at 06:18

Some technics to do that (I won't make here the exact same bottle...):

Knife cut

The cut is straight, but the result is parabolic due to the bottle shape.

Knife project

Again a curved shape obtained from a flat curve.

Create a cutting shape (here a plane)
Scale/orientate it
Shift select the bottle and enter edit mode in the bottle (both are selected and that indicates to Blender which shape(s) will cut the bottle)
Use 'knife project'
In your situation, make sure that 'cut through' is checked

Beveling

In edge selection mode
Select the wanted edge loops
Use CtrlB
Choose bevel depth with Numpad + and Numpad -

Once done, give a shape, for instance selecting the two face loops as below and scale them:

Draw it flat and bend the shape

Use a mirror to make so the future cutting lines will match
Add a simple deform modifier to bend the shape to 360°
Make the cuts/bevels as previously
Apply the modifiers and remove doubles when the shape is as you want
Add a subsurface modifier
Scale and merge (or extrude and model) the shape to fit your bottle

I will try the solution provided by you and then will reach to you master ;-) — Prashant Tomar, Mar 15 '17 at 09:01

Supplementing the options provided by lemon, here is a different approach. Before any other steps, instead of having the vertical edges parallel to the z axis, twist the bottle so that the edges now vertical become helical around the z axis. Adding the groves around the bottle might then be able to be achieved by standard methods of adding geometry.

I agree. This is to add to the toolbox! – lemon Mar 15 '17 at 09:07
