I was experimenting with another post for shrinkwrap, when I had to try the OG !_FilletEdge, I always had the Alias “FE” Mapped to “!_FilletEdge”
Note: This issue persists only when using FE for fillet edge, Changing the Alias to FT or typing FilletEdge doesn’t produce this issue, this makes me feel that there is another “FE” command conflicting with my Alias.
Definitely looks like a Test Command, although it doesn’t remember the “Next Radius” setting. it looks a bit more interactive than the standard filletedge. still works with Polysurfaces only.
