id field with local ucs

[Dibe]

Good morning to all,
I ask politely if someone is able to help me find the solution to the following goal:

use a data field for a "point object" that tells me the coordinate y but referring to the local (non-global) ucs.
using the "id" command provides me with the correct co-ordinate relative to the local ucs but needs a data field that is updated according to the position of the "point object".
I found only the data field that only refers to the global ucts.
Thank you for your cooperation.

okin the end your field should have a formula like this: ryof(w2u(8.464))
It seems complicated, but after some tests you go like a splinter.. .

Good morning gp,
Thank you for your intervention and your precious collaboration.

I tried to do as you indicated but in the preview of the formula remain the 4 "#######" which are then returned as text field data.
of course I set and set the origin of a "local bird" (so not global).

about the formula string like yours, I got this: ryof(w2u(4563454.5651))

the value "4563454.5651" is the actual coordinated "y" (after writing the formula ryof(w2u( I have selected input data field/object/point/position) non of the system "Localucs" of the global one but at the end it displays this: ♪

If it works to you, I don't want to have any modified variables or for my ignorance something else that prevents me from the result you get.

I explain some things, ryof e w2u are two functions of the autocad geometric calculator (geomcal), from the command line you launch by typing cal.
ryof(p) returns the coordinate y of point p (so in theory you could in the fielddati not only scourge y, it would work the same), while w2u(p) converts the p point from wcs to the current ucs.
in my lisp I often use the functions of geomcal, I think they are too neglected by those who make programming.

said this, follow the steps described in the gif...

Thank you very much for your availability, with the gif I no longer have the slightest doubt.
you had already been very clear before, I had done everything step by step correctly.
but at this point, the strong doubt of doing a test to the colleague's computer.. .
There's something that doesn't work in my autocad while my colleague's autocad works!
I tried little bits to use my civil3d and it works!
something that disturbs the regular operation in my autocad.

I think I can reinstall everything from the top with all the icons, commands and custom settings.
thank you thank you thank you. :

I also learned new commands despite autocad use by more than 30 years!
You never end up learning. : )

Well, exporting autocad settings and reimporting them to the new one should be very little to fix. . .

However, do not reinstall, I tried to replicate your error and get it when I imposed the format decimals when choosing the point position.
try to choose Current unit, you can always change later, as I did in the gif.

That was the problem!

it also works to me!!!
I owe you. You were very kind and patient. Thank you!
If I can change it will be a pleasure.
heartfelt thanks as a person and availability. Thank you..

Please:
It remains a mystery as autocad can do similar things.
