Normal

Fills the area inside the shape under the cursor.

Inverted

Fills the area outside the shape under the cursor.

Leak Size

Size in pixel to consider the leak as closed.

Thickness

The thickness radius of the boundary stroke in pixels.

Simplify

Number of simplify steps to apply to the boundary line. Higher values reduce the accuracy of the final filled area.

Advanced

Boundary

Sets the type of fill boundary limits calculation to perform.

All

Use the thickness of the strokes and the editing lines together.

Stroke

Use only the thickness of the strokes (ignore edit lines).

Line

Use only the edit lines (ignore strokes).

Show Lines (grid icon)

Toggle show help lines to see the fill boundary.

Layers

Determines which Layers are used for boundary strokes.

Visible

Calculates boundaries based on all visible layers.

Active

Calculates boundaries based on the active later.

Layer Above

Calculates boundaries based on the layer above the active layer.

Layer Below

Calculates boundaries based on the layer below the active layer.

All Above

Calculates boundaries based on all layers above the active layer.

All Below

Calculates boundaries based on all layers below the active layer.

Precision

Multiplier for fill boundary accuracy. Higher values are more accurate but slower.

Ignore Transparent

When enabled, strokes with transparency does not take into account on fill boundary calculations.

The value slider controls the threshold to consider a material transparent.

Usage

Use Fill Tool to leak material on the new closed area.

When you are satisfied with the fill result you can delete the Boundary strokes using the Clean Up tool in the Grease Pencil Menu in Edit Mode.

Switch to Draw Tool

Use Ctrl-LMB to change temporary to the active draw tool. For example to manually cover small areas difficult to reach for the Fill tool. See Draw Tool for more information.
