I remember hearing somewhere that in Max there was a tool that allowed you to 'paint' objects evenly on a selected edge loop, and the object would align to the normal of the surface you're painting on. I've looked through the object paint menus and can't find anything like this, other than the regular object paint tool with the spacing parameter. Just wondering if what I thought I heard was true or not. If anyone has an alternative to this kind of thing, I'd really appreciate it. I just need to place in a lot of bolts on the exterior of a helicopter and would like an efficient way of doing it.
