Variable width strokes in Adobe Illustrator and how to create (such as using the width tool) and use them with paths tutorial.
The variable width strokes create amazing stroke designs in Adobe Illustrator. They can take strokes to another level using variable width strokes - all super easy.
select a path in Adobe Illustrator
set the width for the path
set the color
select the width profile / variable width profile from dropdown OR use width tool in toolbar
You can use the variable width strokes by using the width profiles at the top of the Illustrator application. You can use the variable width profiles with strokes, with normal paths, lines, circles, illustrations, use them with brushes and more.
The variable width profiles can be modified by using them with the width tool found in the tools bar and saved for use in future projects. You can quickly apply the variable width strokes to any design and create amazing results in seconds such as beautiful drawn ink strokes. You can also use the variable width strokes with the width tool and use that to modify any line in seconds. This tutorial shows how to apply the variable width strokes / width profiles in Adobe Illustrator and how to edit them and how to change the width of lines to create stunning varied stroke widths.
The tutorial on the Illustrator variable width strokes also shows you how to save the width profiles and how to use the width profiles with the appearance panel to create beautiful combinations of lines and strokes. Another key part of the tutorial is how to use the variable width strokes with type to create truly unique type / text designs.
The variable width strokes in Adobe Illustrator can be used with paths as well as brushes.
You can use them to create stunning brush strokes designs that can be manipulated in many different ways and the variable width strokes can be saved to the profile presets section.
The Illustrator width feature is super easy to use, either apply via the Illustrator width tool or via the variable width profiles. You can find the width tool in the Illustrator toolbar about halfway down and it is combined with the warp tool, wrinkle tool and others.
The width tool is an unique tool within Adobe Illustrator but there is a supporting tool set that is available via the Astute graphics site. You can also write your own plugins (and perhaps scripts) to manipulate the width feature in many additional ways. One wonderful tool to use with variable stroke widths is the "WidthScribe" plugin and that can be found on the Astute Graphics website. It is a superb tool for manipulating widths in 1000s of ways and worth checking out via their demo plugin set. I have found the widthscribe tool a super useful tool for all kinds of artwork and some really unique and wonderful art can be generated. I would also recommend checking out youtube video tutorials on the widthscribe (there are a few by me on there as well)
Go to the Illustrator toolbar
Select the width tool (halfway down the toolbar)
select a path in Adobe Illustrator (any path, open or closed) such as line segment or spiral or circle etc
Go to the width tool
make certain there is a path stroke (it will not work otherwise)
Go to the path and hover over the path and you will see a + appear
Drag outward (hold down the alt / option to just drag one side of the variable width profile)
Go to another part of the path and see the '+' appear again
Drag out the width profile
You can use the width tool to create all kinds of unique shapes in Adobe Illustrator by using the width tool to modify the selected artwork.
Click the center of one of the added points for the variable width stroke using the width tool
And drag the variable width stroke point and move back and forth along the path. You will notice that the point can only be dragged so far (in some cases) but this depends on the width. Sometimes the variable width profile center point can be dragged over multiple points.
If you wish to modify the outer points of the variable width profile
click the side you wish to change and drag
Hold the alt / option to alter just one side
You don't have to manually edit the variable width strokes in Adobe Illustrator. You can use the width profiles. Sadly, there are only a small number but they cover many of the obvious design (always surprised Adobe have never added more - they add lots of swatches and brushes but the width profiles are fairly limited)
select a path
add a stroke to path
go to the Illustrator width profile dropdown
select a width profile
You can also add your own width profiles to the document by
select path with a variable width stroke
click the add command at the bottom of the width profiles (found along the top bar of Illustrator)
You can use the variable stroke widths once or add them multiple times via the appearance panel
select a path such as spiral and set to no fill and no stroke
go to the appearance panel (window menu)
go to the right side menu
Add new stroke
go to the width profiles or the width tool and add a variable stroke width (as above) and modify
go to the appearance panel
and add a new stroke
go to the width tool or width profiles
modify the variable stroke width for the Illustrator path
repeat with additional strokes
You can also use the graphic style panel to add a new graphic style (which can then be re-applied to other paths etc)
One thing that is not great with the variable width strokes is that they often leave a lot of points behind when you use the expand appearance command
select path
object menu
expand appearance
Now manipulate the points using direct selection tool etc
The result is not always great and you can always use the smooth tool or as I like to use, the Astute Graphic Smart remove brush (a superb tool) to remove the excessive points. You can find out more about the smart remove brush via the vectorscribe section on the Astute graphics site as well as download a demo of the plugin set. You can also find out more about the smart remove via video tutorials on youtube.
You can use the variable width strokes with type in Adobe Illustrator by selecting some type and then applying the width profile via the appearance panel and adding a stroke and then manipulating the stroke with the width tool etc
select type
appearance panel
right side menu and add stroke
go to the width tool and modify (as above details) or add a width profile and change the stroke width etc
This can be repeated numerous times and you can add effects and more fills and strokes to the mix and even save the result for future use (it is an appearance and they can be saved to the graphic styles panel). You can use the appearance panel and width tool to create all kinds of amazing type effects in Adobe Illustrator. The type is also still live which is great so if you wish to change the letters, they can be changed in seconds without re-starting the width tool etc.
You can also use the variable width strokes in Adobe Illustrator and the width tool with brushes and create some truly unique brush designs and distortions. All the brushes can be affected by the width tool
Select the paintbrush tool
Apply
select a brush stroke from brush definition dropdown (top bar)
Select width profile or use the width tool
With the latest versions of Illustrator, the width tool can be used with width profiles and the new repeat feature which means the designs can be repeated radially as well as grid or mirrored and still be live for use with the width tool and the strokes.
