you are asking to set the positional unitis in acad to 100th of a working unit. This is microstation language as I recall. It simply reminded me of that aspect of the program
Microstation handles its units a bit differently. There are user-specified major unit divisions, and each major unit is divided into a number of user-specified minor divisions. Those sub-divisions are stored as a separate number from the major division number so there can be precise numbers at very large coordinates. But that's at the expense of storage space (needing to store two floating point numbers instead of just one), and it still fails when dealing with large ranges of major units. Everything needs to be in an imaginary working box "box", like trying to keep everything close to the WCS in AutoCAD.
AutoCAD, on the other hand, stores its coordinate values as a single floating point number with equal precision WITH a caveat: very large coordinate values result in less precision being stored (read up on storing floating point values when there's a bit of time - not required reading but provides useful context on why some things do what they do). So while geo-people like everything in meters and geodetic coordinates, it kinda messes up the engineering folks who work with millimeters since the coordinate values explode upwards to the point where necessary precision is lost; cue screaming about solids not revolving and 3D solids not rendering correctly on screen.
And now, for something completely different... aka back on topic.

Yep it sure does. Your users want to pick points, and that is what the graphical user interface is for. The software provides a tool for doing that with precision and that is the transparent command tool bar. The screen cast I provided demonstrates how to use it and how it matched the precision in both plan and profile.
I asked back in post 4 and you replied in post 5 that this is what your users do and is the problem. Then in post 36 I pressed further on the use of transparent command tools and you replied in 38 What is a trans parent command?
A transparent command is the answer to your graphical user interface issue with precision. If you don't want to key in exact numbers with 16 point floating decimal value you have to use the transparent tool bar to take advantage of precision and the GUI.
I don't know how else to explain it. There is no tool to restrict a randomly selected point to 2 decimal places. You have to use the tool as designed or get someone to program a third party app for you.
