Hello, fellow Rhinos, I am trying to cut a groove along the center of the ‘triangles’ composing this Star of David with a Flowed 1 Rail Surface, but for some reason the Boolean Difference isn’t working. Both are solid judging from successful volume analysis.
I first tried this with a triangle to make a sharp bottomed groove around a sharp triangle on the surfaces, but I kept getting overlapping ends. So I did an Arc Blend to round those corners, and the ellipse flowed along that pretty well, I don’t see any weird self-intersections inside the corners, yet still no Boolean Difference happening.
Any ideas? I uploaded the .3dm file
