Free Form Deformation offsetbox failed

[Free Form Deformation offsetbox failed]

Hi 

 

The problem is solved because the parameter which controls the distances of box layers from surface was set wrong by myself. 😅

[Free Form Deformation offsetbox failed]

Hi

 

I'm trying to set an offset FFD box around a plane. After translating, a disorder plane was got as shown in the figure below. I have got a desired plane if the sweep or rectangular box was employed. Could you please help find out why the offset box does not work?

 

Thanks a lot.

 

Best regards
