Line Gallery - Stroke Shapes
The Stroke Shapes section of the Line Gallery lets you change the contour (shape) of lines. (For example, to create a tapering line.)
To change the stroke shape:
Drag-and-drop the required stroke shape onto the object. Hold down CTRL to apply the pattern to an object inside another object. See apply inside.
Double click on the stroke shape to apply it to the selection.
Click the required stroke shape to select it and click Apply to apply it to the selection.
You can also change the appearance of the line using Brush Strokes. See Changing the brush stroke design.
Notes:
Applying a stroke shape removes any arrowhead/tail or dash pattern already applied to the line.
You can also select a stroke shape using the Freehand & Brush Tool.
