Thanx BurrMan,
Really good command, I think I'll use it, did not know about it, thank you very much!

Hi Andrei,

> Very complicated, I think it's very low level for me.

As I've mentioned many times before, really if you want to do direct surface point modification a sub-d modeling toolset tends to be a better fit for that than NURBS modeling.

Some of the things that give accuracy to NURBS modeling do not lend themselves well to squishing surfaces around. Some problems like internal segmentation on circles/arcs/spheres can be avoided though by doing a rebuild on it.

Hello,

Interestingly this is a very good illustration why you wouldn't use loft (left) as a replacement for a more appropriate tool for the task, revolve (right). Same set of curves, just ran the commands. A curvature analysis is shown in the picture. Poor surface quality in the lofted shape which could lead to further problems as it is modified. No such problems with the revolved shape.

As fan of Loft maybe this script can interest you ;)

link of script is on top page! MoveSlicetoPoint
Interesting when you have a lot of slices

Thank you Pilou, intersting script, looks like I'll use it.

While using the Loose option in the Loft tool I wondered if a slider control would be a worthy addition to let the degree of 'looseness' be tweaked to one's liking?

It would be great, but unfortunately I don't know how I'd implement it - the internal details of how loose loft works does not really involve any sort of looseness factor in how it functions. Usually an adjustable slider control for things like that can work when there is some kind of scale factor involved in the calculations, but when there's nothing resembling that kind of multiplying scale factor it's then difficult to include one.

Hi Michael.

Yeah I know that many of my ideas border on the impossible :-)

Thanks for taking the time to reply.

Martin,
you can use this method.

1. Use loft (normal mode) to build a surface; Draw a circle.
2. Select the circle; Array -> Dir;
3. Select the circles -> Loft (caps off) -> Flow tool. Use cylinder as base surface.
4. Now you've got more curves, so you can variate the power of loft by selecting and deselecting those curves.

This method works good with any curves. I could write a script, but, unfortunately, I haven't free time for it now.

Project simple Lines don't give the same result ?

Your method works if all curves parallel to each other.
OK, how about this one? :)

Hi Max and Frenchy.

Thanks for these techniques of refining the loft surface, I wouldn't have thought of either of them!


All the best.
Martin.

Maybe Iso Lines ?

but your methode is surely more versatile!

Great idea!
My method is more accurate and can be automated, but Iso Lines method is more faster and easier.
It will be enough in most cases. Thank you.
