I have specific mesh-object that besides peripheral polygons - has inside polygons
I need to delete all inside polygons OR i need to copy to buffer only peripheral ons

The problem is: when i use selection arrow then i select peripheral and inside polygons.

Is there - houdini possibility to cast a ray onto this mesh object and determine only yhose polygons that a preripheral?
I say abouy first ray-intersection with peripheral polygon and that is the polygon which i need and if the ray intersect the secon polygon (inside the mesh) them delete it and in such a way this proceure is repeated to the end

I think you'll need to provide a picture and a little more clarity here. I'm having a hard time knowing what you're asking to do exactly.
