I'm relatively new to blender and I'm trying to create phone case same as on picture below:
My problem is that I have no idea how to create the shape of the white part of the case. I started off with cube to create rectangular shape, added boolean modifier and added object to camera lens, displayed the camera lens as Bounds, but it resulted in still having rectangular shape with rough corners instead of cutout with rounded corners as I need. What's the best solution to this? Below i showed what i got, but since it's still a rectangle I can't adjust the corners.
