Select surfaces that intersect with 1 polysurface

Rhino Rhino for Windows

Basically I want to use 1 polysurface to select all other surfaces that intersect with it. I have a LOT of simple surfaces on one layer - I want to select just the surfaces that intersect with 1 poly surface on a different layer. Any ideas how to do this with Grasshopper or a script?

TIA

Works a charm… Many thanks. I now have a new button on my toolbar.

I was banging hard on Python a year ago and made a lot of progress but this was beyond me.

Thanks again,
