My first time posting here and hoping to get some help from the very talented users here on the forum. I work for a footwear company and we have started to use 3D files of soles/bottoms from an overseas Mold Shop for design purposes at our headquarters. The issue we have though is that the mold shop’s files have a random amount of surfaces normals flipped and we have to manually go in and flip them to the correct direction for rendering purposes in other software.
As of now I just have the flip command hotkeyed and go from one surfaces to another but this is taking too long especially if the bottom is more complex like the attached picture. Has anyone developed a selection script that can just select all the reversed surface normal or has a faster solution than what I currently am using? I also have grasshopper if anyone has a program in there.
