Thank you - great tip !!
What if I need a larger amount of tweens ?

I am attaching a "spline sketch" done in Cinema as concept for a glass vase.

The modeling challenge is the surface : It is not thought to be clean but
consist of ripples, each ripple being defined by the respective splines.
Adding a second image to show what I mean by "ripples"

easy. Set up the profile lines as i explained in previous post. then you draw another line segment snapped to the end of one of the profile lines. Then make mulptile copies of this new line segment using "Array" along curve. this should give you any set # of copies along the line. Use the trim command to divide the profile line into pieces. then select all the profile segments and join together again. repeat process to create the second sweep profile. 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.

Here is a very quick video of how to setup the multiple tweener curves. Sorry i don't have time to properly edit the cursor timing as I am on my way out the door!

OOPS! try this one...

Very sweet support here thx ;-{)
