When you set the right stroke styles designing gets so much easier and faster.
Stroke style panel
You can add and adjust stroke styles in LTTR/INK panel.
Create a new stroke style from existing ellipses
Update a stroke style
You can update stroke style in "adjustment mode" in the LTTR/INK Panel.
Or just select the ellipse with asigned stroke style directly on canvas and start adjusting.
All the other ellipses with the same stroke style applied will be changed automatically.
If you wish to adjust just one ellipse separately, click on the "broken chain" button.
The selected ellipse is now free of any stroke style and can be adjusted separately or asigned a new stroke style.
NOTICE: To apply the stroke style the "adjustment mode" has to be SWITCHED OFF.
The order of your styles in the panel is fixed – the newest style always on the top of the list – and it cannot be changed.
