How are Aircraft Noses Designed? Look at the Learjet, Embraer and Boeing noses which are kinda pointy - drag efficiency aside, how do they come to the final design of the nose?

I’m talking from an aesthetic point of view - how do they design them to be aestheticly pleasing as they are?

By hand, CAD software or other? I don’t think it’s random guesswork I produce what looks good and what doesn’t - do my question is: how do they make them noses?

I don’t think in the early days of the 737 they had advance mesh modeling like we do now!
Aesthetics are by far and away the last thing aircraft designers are optimising for. A better question might be, why do aerodynamically-efficient designs look pleasing, but that would likely be an art or psychology question and off-topic here.

Since aircraft could travel at appreciable speeds, designs have focused primarily on drag reduction. Smooth curves and teardrop shapes on the leading parts of shapes help with this. Before 3D fluid modelling software, this kind of design would be achieved using a combination of fluid dynamics computations done by hand, wind tunnel modelling, and likely a bit of intuition.
