Hello everyone,
I want to use some curved arrows in a picture.
I don't want to use a difference between a torus and a box.
Does everyone have an idea ?
Thank you ,Jens.

Lots of spheres close together in a row?

Why not?
Alternatively you can use for example:
- difference between lathe and box :-)
- several patches (modelled with spatch for example)
- union of a lot of cylinders and spheres
- in megapov: sphere sweeps

Well, how about a difference between a torus and two planes?
Why don't you want to difference a box from a torus? That method is
perfectly ok...I think your only alternative to a torus CSG of some sort
would be a bunch of cylinders and spheres used to imitate a torus, an
isosurface, or a mesh, all of which would be a lot harder and take much
more memory, and render slower.

Wow, that's one obfuscated message!
I can usually read HTML formatting, but this one had me beat ;)

I think it's always a good idea to tell why this kind of decision
(ie. discarding a solution which sounds good at first glance) was made
if it's not obvious, as in this case.
If you tell why you won't be using the easiest solution, that will help
people understand your needs and give you a better answer (or alternatively
correct misunderstandings).

Hello,
the background for my problem: I want to generate some scenes, where some
objects rotate.
I want to mark the angle of rotation with a curved arrow.
Sure, I can use some difference between two (or more) sets, but, I thought
there are simplier ways to
generate this curved arrow.
Thank you, Jens.

Jens,
You can easily make some very nice arrows that will look like ribbons floating in
the air using either spatch or hamapatch, both of which are excellent free
modellers. The only caution: if you make them flat (not out of a flattened tube
or something like that), the panels have no thickness at all (a lot like a
polygon object), and if your camera gets edge-on, they will essentially
disappear. This can easily be avoided, however.
See the POV web site for links to them.
HTH !!
