Farthest X and Y coord in a drawing

[popescu.gabriel.catalin95]

How would one find the farthest X and Y coord of a drawing?

Assuming I have a line placed from (0, 0) with a lenght of 200(units) the output will be (0, 200). If I place another line from (500, 500) with a lenght of 200, now if I run the command the output will be (500, 700) .

Screenshot maybe explains it better.

Hi and Welcome to AutoCAD Forum ,

Still your issue need more clarification to catch well the point that you asked for .. But as much as i understand your need you can use ID (Command) to display the UCS coordinate values of a specified location . also by COORDS (System Variable) to control whether the cursor position on the status bar is updated continuously or at specific times only. It also controls the format in which the coordinates are displayed. >> Click <<

Type in the command line 

(getvar "extmax")

and 

(getvar "extmin") 

to get the coordinates of the smallest rectangle around all your drawing objects (also on hidden and frozen layers).  

Or draw such a rectangle this way: 

Command: Rectang

Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: (getvar "extmin")
(112.187 173.172 0.0)

Specify other corner point or [Area/Dimensions/Rotation]: (getvar "extmax")
(553.477 542.498 0.0)

Thank you very much!

If I understand your question correctly the answer depends on how much precision you want for the line length. AutoCAD uses a floating point database of about 15 significant figures.  Therefore, if you want a precision of 0.0001 then the maximum coordinate would be about ten billion, i.e., 10,000,000,000.0000 (15 digits).  If you can settle on a precision of 0.01 then the max is one trillion!

You should do a ZOOM All or a ZOOM Extents before getting the values of the EXTMIN & EXTMAX System Variables.  Those adjust outward whenever you add objects beyond the former extents, but they don't adjust inward when you do something that reduces the extents, until one of those types of Zoom [read about it in Help].  So if something has been Moved or Erased that shrinks the extents in any direction, and you don't Zoom A/E before doing your thing, you will get an incorrect result.

Thanks for this important addition.

I figured out somethig was wrong when adding elements... I solve it by swaping layers and regenerating model, but your solution is interesting as well, and it works.
