<label>This effect joins the Bezier curves with straight line segments.

If the end nodes are close enough, they are merged into a single one.
|
||||
With the optimized option selected, the new curve starts from the top
|
||||
most curve from the selection. The curves are then joined based on the
|
||||
distance of their closest end point to the previous curve.
|
||||
|
||||
Additionally it allows to create different tabs / dimples for lasercutting.
