Sweep nurbs shape A to shape B?
Hi guys,
There’s something I can’t figure out but I guess one of you will know the answer…
What I want to do is make a ‘wire’ (using splines), the start of the wire would be a letter shape and would evolve to just a circle shape.
something like this: https://i49.tinypic.com/ac3cxg.jpg
So is it possible to make some sort of a sweep nurbs object in which the start and ending shape are different? Please let me know!
Thanks,
Sven -

Sounds like you want to use the Loft nurbs rather than the sweep nurbs. It can be a little tricky as you’ll get bad results unless the splines you’re sweeping have the same direction and number of points. In this case I’d start with the letter spline, make it editable, copy it, and then form the points of the copied spline into a circle using a circle spline as a guide with spline snapping turned on. Loft the two splines. Then I’d deform the result with Mograph’s SlineWrap.

Thank you for your reply, but indeed, this gives very bad results, even when I make sure the amount of points is exactly the same…
There’s got to be another way! 🙂

It doesn’t have to give bad results. Perhaps you aren’t using enough divisions in your loft and/or deformation spline?

Ok, I already got to the point that the letter is transforming into the circle (I had to rotate it around a bit). But how do I use the Splinewrap to extend and bend the tail?
Thanks

Splinewrap deforms any object along a spline, so you drag & drop the path spline into the splinewrap’s spline box, then place the splinewrap and the loft nurbs objects under a null (deformers work on parent or sibling objects). You will probably have to adjust the splinewrap’s Axis setting to get it looking right.
