So I was modelling a weld-ment structure. During modelling, i created a series of holes to insert bolts on one side. Now I want to make  similar holes on the other side.

I tried to do a mirror, but get error (coz of multi body part?). So i made a derived sketch from previous hole wizard's sketch onto the other side surface.

Now How do I use this sketch (of points) to make the holes without creating another feature?

I know I can sketch point such coinciding with previous sketch points but i feel there is a easier and faster way.
