Returning vertical surfaces which face my building

You might also be able to use the same logic as found here:

Isovist Challenge

I’d like to pose a challenge to the Dynamo community: Using only native dynamo nodes, create an “isovist” function that accepts the following inputs: a Point representing the viewpoint a list of 2d curves representing any possible obstructions a number N representing the number of sample points a number R representing the maximum vision radius and returns a polycurve by points representing the visible polygon from the viewpoint: [image] The resulting polygon should terminate at the circle …

You can get a surface that maps the closest intersection from your building and use the perimeter to intersect with vertical surfaces.

Just an Idea.
