After various tries, I add that straight views always accept the style of tangent edges whatever it may be, and that iso views always go in hidden tangents
tried this trick on your bottom image, you selected the middle icon as the template. Instead, take the second one that will make you see the hidden lines like when you do classic industrial drawing.
Indeed, as the model means "like the 3D model" in which if you don't put yourself in transparency, well you don't see the holes and other hidden machining.
Solidworks makes us smart (it's the hidden functions that say "try again") we have to interpret what the hover message of an icon means.
