Guess the polyhedron face vertex order definition you are referring to Looking inwards Unless OpenSCAD reverses all faces in polyhedrons when writing to STL, I Order is counterclockwise (CCW) when looking at the face from outside The recent thread about STL referred to a format description where it isĮxplicitly stated in text and with a figure that the correct vertex Polyhedrons, and I observed no issues when I did that.
