Mating Objects Assistance Needed

I am new to Rhino 5.0. I am having problems trying to ‘mate’ flat bottom rivets on to a curved face of an automotive grill frame (see attachment). Any assistance will be appreciated.



try OrientOnSrf

Hi Larry, I haven’t looked at your file, but if someone else doesn’t chime in , I think a real manual way would be Orient 2 Pt. You would have to place a target curve where you want the rivit to go. First run Orient2Pt, then pick 2 points on rivit, then 2 points on that target curve… it’s a start.
I am sure there are much better ways. —Mark
