"Now you can use "Sweep" as explained earlier and the resulting output will be a polysurface. Highlight select the edges on the polysurface and Copy/Paste to extract all of your tweeners..."

I have done it this way but stopped after obtaining a polysurface as attached.

1) I did not figure out how to tell MOI how MANY tweens I wanted to obtain
as no respective dialog popped up ??
2) I did not know how to highlight the tweens ??


Second attachment is a "rippled" surface done in Cinema.
