You can create a blend from two or more paths that have the same fill and stroke
type. Blending creates a series of intermediate objects between the original paths.
Beginning with the bottom object in the stacking order, each intermediate object's
shape, stroke, and fill becomes closer to that of the object at the top of the
stacking order.
Freehand creates a blend as a group of objects. Ungrouping a blend discards its
blend properties.
You can modify a blend using the Object inspector or by modifying a subselection
of the blend group. FreeHand automatically regenerates the blend.
You can create a blend between selected points on the original objects, creating
different results than an object-to-object blend. The selected points determine the
shape of the intermediate blend objects. Path direction can also affect blending.
