cool!

just built meself a cube with this idea wich might come in handy!

If I may, there's a secret for this process to work: you need to select the generated surface have "Show pts". (I guessed right, didn't I?)

Cheers,

Hi Diego, yup that is correct - select the surface and use "Show pts" to turn on its edit points.

One quick note about "Show pts" - it does not work on all solids, it only works on a solid if all the surfaces touch one another at a "natural edge" rather than a "trimmed edge".

There is some description and illustration of that here:

But you can always use "Show pts" on an individual un-joined surface though.

There seems to be a bad bug in using this technique in the latest Nov 12 beta.

When you go to pull points around after extrude->setpath, it adds edges to the surface which crease when points are pulled.

Edit
Did some further testing, it only happens when using polylines. Still works Ok when using curves.

Hi kev, that's not a bug, it's normal for the surface created in this way to inherit the exact same nature of the curves that are input into it.

If you input a polyline, then the generated surface will behave like a polyline in that direction too, and when you pull around points of a polyline it makes sharp corners, so the surface created in that way will have sharp creases in it in the same way. When a surface is edited in such a way that it develops a sharp crease in it, it gets divided into separate pieces at the crease area, that's where those edges come from.

If you want it to deform smoothly, you'll need to give it input curves that would deform smoothly themselves, that's why the original instructions mentions using Draw curve / Control points specifically.
