Gap closure lines are automatic temporarily lines that help to close gaps on the strokes.

Control the Size of the line extension or the circumference to use to calculate the lines that will close the gaps.

Sets the type of Gap closure method to use.

Uses the Radius of circumference of opened nearest points to calculate a line that close the gap.

Extends the opened strokes to close gaps.

Check if extend lines collide with strokes, stopping the extension if a collision is detected.

Use for closing gaps only if the extend strokes collide.

If you have a large gap in an area that you want fill, you can add boundary strokes manually, a temporary auxiliary lines for closing open shapes. To create a boundary stroke use Alt-LMB and draw a line to close the desired area.

### 自动间隙闭合#

A more automatic way to close gaps in an area that you want fill is using temporarily helper lines. There are two method to use "Radius" or "Extend"

Radius use temporary auxiliary lines calculated from the radius of nearby open points to close open shapes. Set the size more than zero to control the circle size over opened points (the circle will disappear when the line close the gap). Click over the area you want to be filled and change the length of the strokes using PageUp PageDown or Wheel. When you are satisfied with the length and you are sure the temporarily strokes cross each other, click again to fill the area.

Extend use temporary auxiliary lines extending the actual strokes ends for closing open shapes. Set the size more than zero to use the extended lines, click over the area you want to be filled and change the length of the strokes using PageUp/PageDown, Wheel or a pen's MMB. When you are satisfied with the length and you are sure the temporarily strokes cross each other, click again to fill the area.

### 切换自由线工具#

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.
