Rhino 3D Help Forums

I've generated these surfaces with Grasshopper, so there will be 100s of these surfaces.  Is there a way to trim the surfaces where they intersect (I can find the intersection (yellow line) with <intersect> and window everything.)  I can do it manually, but is there some command or method that I can script?

I'm not sure what kind of surfaces are these, are they touching each other? Are they like stripes forming this shape or what?
You can try maybe if these are touching, join first all the surfaces on one oval group, and on the other, and trim it once, then explode the surfaces back.
I could really be of more help if I know what kind of surfaces these are. Maybe post a model or smth.

Thanks for the reply Ivan,
Attached are the GH and Rhino files. 
The surfaces were generated with a Sweep1 command.  The rail is a cantinary components.  The profile was generated using a Arc component. 

This is a very simplified example so that its easier to figure out.  The length and depth (Z ) of the surfaces in the complex model are generated using a GH random number component.  So, the surfaces will over lap randomly, so I can't trim one pair and copy. 

Here's the GH file
