Modelling a plastic bottle

Using Polygon Modelling

Create a background template as before using basic geometry then freeze all and make them see-through in object properties. Position on absolute zero.

 





Create a standard box and convert to editable poly, place on zero.
Top poly,extrude 50mm, bevel and extrude again for the neck.
Unfreeze the original object, and name the layers of poly bottle and draft. 
Hide the original. 

Ctrl-Selecting bottom edges of the base and use chamfer to smooth edges. Edge loop the shoulder ring of cylinder and also the bottom of the bottle neck and chamfer .


Check the result in the editable poly. Resembles a bottle now but needs filled out more. Remove the top polygon.
Select a shoulder edge and ring then include select all and connect.


In top level, top view select all middle vertices and scale out (x,y) to meet the outer edges of the original object.
In side view, polygon level,select down from shoulder chamfer and scale out in x,y in top view until it conforms to the original.



Select central 'label' polygons, and extrude to a negative value at a local level.Select top edge of label shoulder, loop and chamfer by 1mm. and repeat with the bottom label chamfer. Inner edge has a tighter edge chamfer of 0.1mm.







Defining the shoulder of the bottle, ctrl-select all polygons, extrude and bevel for design. Ctrl-select all bottom polygons and extrude and bevel for outer base design.










The shell modifier is adjusted to 0.5mm. The centre polygons are selected and modified with the FFD 3x3x3. Change from top level to control points. Try to change the result to FFD 5x5x5 and check the end result. Cut whichever modifier does not work to best effect.

Final render with bend modifier

Turbosmooth modifier can be set to 3 iterations for a sharper definition.
