Accurate manipulations with dimensions

Precise sizing. Why not make more precise, logical size manipulations!? In Blender this is a huge problem, yes there is a program cad, addons... but it seems that this is the tool, the logic that should work out of the box, no? Faced with an elementary problem: Ring D1 - 3.14mm, another 4mm must be squeezed out of it along the X, Y axes in order to get D2 - 3.54mm, the wall thickness of the future cylinder. This cannot be done by extruding an existing ring!! (I didn't find a method to do this) Tried: (ring D1 + E , + )

• S + 1 (nothing happens)
• S + 0.4 (the most logical use of the relative size, but no .... it's not even clear where the countdown is from, the size is not correct)
• S + 3.54 (the same.! With the calculation that is considered from the origin of the point)
• S + 0 to set the zero point, and subsequently make S + 3.54 (where the points connected in the center of the object, and when the ring is separated, they are connected in a strange way).

My solution was reduced to a solution with a second 3.54mm ring and a bridge connection. But this method is not at all convenient in some situations, you have to work by eye! Please, please... Well, that's not right... Add a function in the settings, viewport (button, checkmark, "precise manipulations") - where the algorithm will act differently, which will help to make manipulations for more accurate modeling, I really love Blender and don't want to learn and switch to other software, at that time, when I know what potential the program has. Lord, this is elementary logic, please fix the simplest manipulations in some way.
