Twisted multiple extrude

[RussU]

Hi all,

 

I'm scratching my head on this one... Two simple polylines to multiple extrude.

 

I want to go from bottom one to top one, smoothly. So Multiple extrude is the way forward.

 

So I put them on the same plane and execute the command. I get a twist.

 

The vertex count is the same in both profiles, and the direction of draw is the same, but it does seem like that the "start" vertext is in a differenct place. In other packages you'd choose the vertext and then "make first" on both profiles, to get the right ones to line up. But I can't work out how to in VW.

 

Have tried a convert to nurbs and do a no-rail loft, and I get the same result.

Any clues please?

Why wouldn't you convert to NURBS and loft the curves?

Thanks @cberg but I tried that, and it gave me the same result....

when you loft the curves do you generally select from the same area?

Have made thesame in a subdivision surface, but still curious about the multiple extrude problem...

Yes, I do... so I get the red preview line going between corresponding vertices so I'm not getting expected results

Hi Russ

 

Loft tool should work. Its just about the alignment of the points
