Is it possible to add instances along a path or surface of another object? If not, I'll add a feature request in the appropriate forum...MG
I think you should be able to add instances on the surface with the Merge tool and the On Pen option. I haven't tried that but it should work. Could be handy for adding very details bolts or rivets maybe.
I just noticed that Cut & Clone also makes instances, maybe other tools as well. This is great but you have to be careful. When you check that instances box on the merge panel it stays checked for that tool and all others. SO if you use it to merge then later use Cut & Clone it will be already checked.
