Thank you very much for your help to all who have answered. This was important for me and now I see solutions for my problem.
I am trying them and will go back to this thread to report on the results.
Of the solutions that have been proposed, what seems closer is inplacetexteditor using dbtext instead of mtext, as in [CommandMethod("EnterLengthsDbtxt")] . This is because with dbtext you end edition by pressing enter, so it is simpler. With mtext you have to press Ctrl-Enter.
REGARDING THE SOLUTION WITH INPLACETEXTEDITOR ( [CommandMethod("EnterLengthsDbtxt")])
I would like a possibility of controlling the navigation keys: for instance when the user presses the up arrow key, the editing focus should go back to the previous segment.
REGARDING THE SOLUTION WITH SMALL FORM
This solution was proposed earlier and it would be great since it would also work on older autocad versions. I have 2 difficulties in implementing it:
Problem 1) Manage the navigation keys: When the user presses enter, it should go to the form in the next segment (without needing to press ok button), when the user presses the up arrow key, the editing focus should go back to the form in previous segment.
Problem 2) How to convert from autocad coordinates to screen coordinates needed to position the small form
REGARDING THE SOLUTION WITH GETSTRING
It seems the getstring input field appears at the cursor location, it would be enough to be able to change cursor location, but don't know if this is possible or how to do it.
REGARDING THE PROPOSAL TO LOOK AT CONSTRAINTS:
>> how you will handle changing the lengths
>Just a short interrupt: have you looked into constraints?
Sorry I don't know what constraints are
THANKS FOR YOUR HELP, THIS IS IMPORTANT FOR ME.
