Blend Curve with Same Profile

Hi,

Is there a way to blend curves with the same plan?
When I blend the two sets of curves, although the original curves have the same plan, the blended ones do not.
How should I achieve the target without manually manipulating the control points afterwards.


Thanks a lot!
Ian

draw the first set of curves.

then use _shear for the second set.
