Hi McNeel team,
Normals direction is very important for our work. And we use special backface color on most of the time while modeling to see normals direction, open faces, etc.
I’ve noticed many tools in RHino think that normals are not important and they seem to somethings decide normal direction in new surfaces created to be completely arbitrary. And then there are tools that are outright disrespectful and flip the normals of what’s already there, like this _Cap command.
That’s a big no-no. OK?
