I have this sheetmetal part thats bent at an angle. And of course there's a round at the bend. I want to create a tangent point directly on the surface of that round. The problem I get is that when I create one, when ever I unbend it to a flat state, the tangent point does not follow. I have tried make the tangent point on it's flat state, then bending it back up. Neither way is working... the tangent point doesn't follow... I'm getting desparate...does anyone know of a way...?
