Stroke Tool Properties View

Icon Tool Name Description
Draw Stroke as Straight Lines

Enable the Draw Stroke as Straight Lines option if you want the new strokes you draw to be a perfect straight line. Disable the option if you want the stroke to follow the mouse gesture.

Connect Line Ends

Enable the Connect Line Ends option if you want the start or end point of your new stroke to connect to your existing strokes to make sure no gaps are left in your drawing.

Auto Fill

When enabled, drawing a closed shape will automatically fill it with the currently selected Paint colour.

Trim Extra Lines

When enabled, drawing a closed shape will automatically remove the outstanding lines.

Align Handles After Trim

When the Trim Extra Lines option is enabled, enable this option to make the point where the beginning and end of the stroke meet into a smooth curve rather than a hard corner.

Auto-Flatten Mode

By default, when drawing on a vector layer, each new stroke is created as a separate drawing object, which can be edited independently from other parts of the artwork. When enabled, the Auto-Flatten option automatically merges strokes into existing artwork.

Apply to Line and Colour Art

Allows you to perform drawing operations on both the Line Art and Colour Art layers of your drawing simultaneously.

NOTE If you have Overlay and Underlay Art layers enabled, they will also be affected when this option is enabled.

Apply to Synced Drawing Layers

If the currently selected layer is synced with another layer, the tool will work on both the current layer and its synced layer.


You can modify the central line smoothness of your line using this option. This parameter smooths the initial movement of your line. Increasing the value will result in a smoother line with fewer control points. Use the left and right arrows to increment the value by one full unit. Use the Up - Down slider to quickly increment the value.
