Is such markup required when building a logo?

Question

Geometry

Question for professional graphic designers / logo makers.

In the presented logo, all possible distances / radii are carefully calibrated. What is the best editor to use for these calculations? Do these drawings help to make more beautiful and geometric correct logos? Do I understand correctly that such techniques were used back in the pre-computer era, when each logo was created taking into account such techniques for subsequent copying and competent transfer of the logo to other planes. Are such calculations necessary now?

Answer 1

Such things are not needed now, this is all pathos for presentations.
For high-quality work, you need to feel the proportions, composition, smoothness of lines, etc.
