Avoid Blend is a new blending mode besides Groove Blend.
This blend mode is basically a soft subtraction, followed by a hard union, but it avoids duplication of strokes and computations.
It can be applied to Union and Subtract Boolean operations (the difference is which object is softly subtracted.)
Inflate defines the gap between strokes. You can use only inflate (blend = 0) or only blend (inflate = 0) to see how the parameters affect the appearance.
Chamfer blending can also be applied to this mode.
One usage of this blending mode is Splitting objects (like the curved doors on a car) . You can put the strokes of the door in a subgroup, and then use this mode to add the door to the car with gaps and seams.
