Question

Bend a straight, swept and mirrored part

This lever is currently straight, but I want to bend it so it resembles the right sideview.

Search for tutorials on YouTube or look in Help about Spinal Bend. It's quite simple for this one. Make a sketch that is the bended profile. Use that sketch in the Spinal Bend feature.

@magnus.salomons has explained one method to bend your existing flat geometry.

 

I have posted an example of an alternative modeling approach. In this example, the sweep trajectory for the round bar is created using two datum curves taken from your reference drawing dimensions. The intersection of these curves yields the 3D trajectory for a sweep creating the solid part.

 

I use spinal bend but it would not be my first choice to create this particular geometry. A Creo 4 part is enclosed for reference.

Actually, projecting a true arc on an inclined plane like that will yield an ellipse in those bends.  In this case, if he didn't need the "flat pattern", I wouldn't use the spinal bend (one of my fave tools), I'd instead wrap a curve onto a surface mimicking the angled trajectory and simply use that as the trajectory.  This way the radii are true arcs.

Thanks for the replies, it's fixed now!
