Create a dashed stroke

You create a dashed stroke by adding any number of dashes and gaps to the Dashes property group for the stroke.
The dashes and gaps in this property group are repeated as many times as necessary to cover the entire path. The
Offset property determines at what point on the path the stroke begins.

Animate the Offset property to create a moving trail of dashes, like the lights on a marquee.

Expand the stroke’s property group in the Timeline panel.

2

Click the Add A Dash Or Gap

button to add a dash and gap to one cycle of the dashed-line pattern that you

want to create. You can add up to three dashes for each stroke pattern.

Modify the Dash and Gap properties to make the dashes and gaps the lengths that you want.

Line Cap options for strokes

The Line Cap property for a dashed stroke determines the appearance of the ends of the stroke segments (dashes).

Butt Cap

The stroke ends at the end of the path.

Round Cap

The stroke extends beyond the end of the path for a number of pixels equal to the stroke’s width. The cap

is a semicircle.

Projecting Cap

The stroke extends beyond the end of the path for a number of pixels equal to the stroke’s width. The

end is squared off.
