Seeking Help to Export Edge Convexity/Concavity Degrees as Shown in SketchUp

[DanRathbun]

My brain is being tickled by a quirk involving the Geom::Vector3d#angle_between method.

Searching the forum …

Okay, yes YOU also asked about this method’s quirkiness in a related topic on the concavity of edges in September of 2019. Julia Eneroth gave you an answer and a solution at that time …

Ruby angle_between issue

Hi guys wonder if someone can help. I am trying to differentiate the difference between an internal corner and an external corner to get two different angles as shown in the attached image. [Capture] This is the code I am using, which is returning the same angle for all…? puts (sel[0].faces[0].normal.angle_between (sel[0].faces[1].normal)).radians Any help would be greatly appreciated. Thanks
