Drawing prints different line weights for some radii

[dmk166]

Hi, when I print this some of the curved lines are lighter than the rest. I think I changed all line thicknesses to be the same. Display line widths shows all the same thicknesses and changes all of them if I change to thick, medium etc. But always prints the hole and concave and convex curves as thin lines. Fusion 360 print preview shows them all the same thickness too. Thanks for any help.

I see when you click print there's another box that says "print line widths" --- that needs to be checked.
