Filter by Normal
Filter or select faces of geometry based on their orientation.
Inputs
north
A number between -360 and 360 for the counterclockwise difference between the North and the positive Y-axis in degrees. 90 is West and 270 is East. This can also be Vector for the direction to North. (Default: 0)
geometry [Required]
Rhino Breps and/or Rhino Meshes which will be broken down into individual planar faces and filtered based on the direction they face.
orientation [Required]
Text for the direction that the geometry is facing. This can also be a number between 0 and 360 for the azimuth (clockwise horizontal degrees from North) that the geometry should face. Choose from the following:
up_angle
A number in degrees for the maximum declination angle from the positive Z Axis that is considerd up. This should be between 0 and 90 for the results to be practical. (Default: 30).
down_angle
A number in degrees for the maximum angle difference from the newative Z Axis that is considerd down. This should be between 0 and 90 for the results to be practical. (Default: 30).
horiz_angle
Angle in degrees for the horizontal deviation from _orientation that is still considered to face that orientation. This should be between 0 and 90 for the results to be practical. Note that this input has no effect when the input orientation is "Up" or "Down". (Default: 23).
Outputs

sel_geo
Selected faces of the input geometry that are facing the direction corresponding to the input criteria.
