RayBounce to get wall surfaces

1

Hi,
This is probably an easy one to solve but I’m trying to use the RayBounce node to pick up the surfaces bounding the room. At the Moment I can only get the floors. What am I doing wrong here?

Hi, I think its weird that you get any results at all, as you’re not specifying a vector. Could it be an idea to use Element.Geometry on the room object itself and extract the surfaces thereof?

Thanks for the quick reply.
I thought of doing this before but I’m not sure how to get the material properties of the surfaces - if that is possible. I’m pretty green with Dynamo, sorry if I ask stupid questions.

Check this - MaterialElementId from GetRegion from Face from GetBoundingElementFace

Thanks Petar.
I tried the python script but got an error on line 42 saying Name ‘normalZ’ is not defined. Looks like that whole example was way above what I know. Unfortunately, this may have to go into the too hard basket…
