Uniformly distribute geometry on different edge groups

[Tokezo]

Hello everybody.

I have a task to make an asset. I'm pretty new to Houdini, but I'm familiar with some basics. What an asset must do:

1. We have a geometry, on which we select several edges by hand
2. Place these edges to different groups. I don't know how to do that
3. Convert edges to splines(I found a python script for this)
4. Place geometry on different spline groups, so they don't overlap each other and we can parametrically define an offset between them. I also don't know how to do this.
5. Control the scale of each element by spline ramp.

Here are some pictures. On first we have some edges and we need to put them into different groups, marked 1,2,3.... On the second picture we see the scale of the geometry that we placed on the edges. For example on group 9 we have smaller geometry scale on the sides, which gets bigger in the middle

 

I hope i described it right. Thank you for your help!

2/3. It's trivial to place split geometry on different groups using Partition node. You can even transfer it back to original geometry.
3. Try Dissolve node instead.
4/5. Polywire it. You can control the width of the Polywire's output geometry. Setup ramp parameter in VOPs or Wrangle to map width to arbitrary shape you need.
