This is what we’re looking to build with this tutorial.
We need two symbols for mapping to our final 3D object; a bottle label and some texture for the screw top. Make yours with similar proportions to those shown below and use whatever designs you wish. Group the label components (Objects > Group) to make a label group and also group the top texture components.One thing to bear in mind is the use of gradients within these symbols. Illustrator will rasterize gradients when applying the symbols to 3D surfaces. This is fine and may well give you the desired effect, but in doing so you’ll limit the scaleability of your final object.
Open the symbols panel (Window > Symbols) and drag each of the two groups into the window. Depending uponwhich version of Illustrator you’re using, you’ll either be presented with the Symbol Options dialogue automatically, or you may have to double-click the symbols once they’re in the panel.
Either way, enter a name for each of your two symbols within the Symbol Options dialogue and click OK. You may also find it useful to display the Symbols panel as a list (as shown in the image below), which allowsyou to see the symbol icons plus their assigned names. Existing instances of the symbols on your artboard may now be deleted.
I’m now in Outline mode (Command + Y to switch between Preview and Outline) while working with simple vectors, but you can choose which view mode you prefer.
Use the various drawing tools to form the shapes needed for a silhouette of a cola bottle. Align themall centrally, but don’t worry if the whole thing isn’t perfectly symmetrical, we’re going to slice it down the middle anyway. There are many approaches to preparing shapes for revolving, this way gives you a reasonable impression of the final form before you applied the 3D effect.
Use the Pathfinder tools to join the shapes. Then expand your shapes so you then have one complete object.Step 5
Draw a line vertically down the middle of your bottle object. Then align the two together centrally. Now click the Pathfinder’s Divide tool and Expand the result. Your object will have been split neatly in two.
Ungroup the two halves (Objects > Ungroup) and delete one of them. It makes little difference which of the two halves you delete; more on this later.
We’re going tocontinue splitting our object up, this time with a series of horizontal lines. What we’re aiming for is a collection of pieces so each area of the bottle can have it’s own color and transparency properties.
Start with a line to separate the bottle top from the rest, then one which will begin the label, and another for the plastic underneath the label. Continue with this method until your designmatches the image shown below.
Once again we turn to our Pathfinder Tools. You’ve no need to group the horizontal lines together, just select everything on the page and click Divide. Expand your object as you’ve done before. Then ungroup (Object > Ungroup) to release your bottle sections from each other.
Use the Direct Selection Tool to select four of the nodes along theedge of your object (as highlighted below). Then press Delete to remove them. This should leave you with a segmented vector defining the outer edge of half of your bottle.
If you’re currently working in Outline mode, switch to Preview (Command + Y) so we can determine some colors. Give each of the five bottle sections a color and leave the stroke width at it’s default of 1px (the strokewidth will effectively determine the thickness of your bottle’s plastic, you may want to play around with this).
Select all your bottle sections and group them together (Object > Group). This is a simple but crucial stage in the 3D revolving process. We want all the sections to be treated as one unit and for the effects to be applied to the group as a whole. Without grouping them,...
