Hi,

I've also posted this topic on Odforce and will cross post any solutions that come up.

http://forums.odforce.net/index.php?/topic/16492-cutting-curves-with-spheres/ [forums.odforce.net]

I would like to get the intersection of multiple curves objects with multiple nurbs spheres. I can also work with polygons. but I need to keep the scene clean. So doing things like polywire -> cookie wont work unless I can somehow get back to my lines.

here is a file with a solution of getting the internals of the sphere. but I still cannot get the lines between the spheres.

Thanks in advance for any help.

cheers.
a.

Soo,
I think I found a solution. but its really dirty and I feel horrible about it.

Check it out and please let me know if there is a cleaner way.

I can't sleep thinking there is no other way that is simpler.

Here is another thread that covers this.

basically its a way of getting information from one chain of sops to another that has the same point order and count. Although this has also been used in clever ways by other people.

Here's an alternate method, maybe a bit cleaner.
