You can use multi replicate with offsets in bryce. You can also multi replicate along a curve. You can also import objects from other programs. Some people use programs called Wings or Spiralizer. I use a program called Rhino. Gevidal and Rochr have hundreds of gallery images. Maybe you could link to one in this post. Better yet copy the image and circle the parts you mean then post it to this thread. Then we could tell which objects you are talking about.
