Thanks for the response @Vladimir

Would you know which of the ootb nodes you think I should use?

Some which come to mind are:
Geometry.IntersectAll
Geometry.DoesIntersect

will be better, you can just add Element.solids before and replace Element.IntresectSolid from Bimorph.

Hi @Vladimir - I think I get what you mean will change and send you a screenshot of the graph for you to confirm the logic - Thank You!

As an update here -

This is as close as I have come to a feasible solution.
The clash and non clash regions are set the category “Lines” as part of the import - which I am sure can be improved.

If anyone wants to comment on the inefficiency of this script, please feel free to contribute.

Thanks.
