I'm confused about "R34 2 PL" means.
I'm guessing the radius of the round is 2mm and the curve is a quarter of an ellipse like so:

Am I right?

It should mean radius 34 in two places - ie same on right and left locations on casting . Actual profile is made up of an arc segment of the given radius and there may also be short sections of straight run off lines .

That's what I thought but a radius of 34 is impossible because the vertical distance from the top to the bottom of the curve has to be 60

It's a quarter circle merging into a vertical line .
Ah I got it now. Thank you for your help
