Satin lines, both open and closed, include a ‘calligraphy’ setting which allows you to specify an angle like an italic pen nib. Generally you will use this setting with Digitize Open Shape but it can also be applied to Digitize Closed Shape with line stitching selected.
Tip: The same setting can be used with Freehand tools to create more interesting ‘calligraphic’ effects. Pour plus amples informations, voir Freehand.
