Label Lat/Long

[Jonathan3891]

I found this lisp that alerts you the lat/long. What do I need to do to make it label the lat/long? I've tried several times to get it to work with no luck.

Thanks!

(defun c:get_ll (/ as_cor ll lat lon pkpt)

(setq as_cor (ade_projgetwscode))
(if (/= "" as_cor) ;checks for an assigned coordinate system
(progn

(ade_projsetdest "LL84") ; uses lat/lon with no datum change as
needed

(while (not (setq pkpt (getpoint "\nPick Desired Point: "))))
(progn
(setq ll (ade_projptforward pKpt))
(setq lat (car ll)
lon (car (cdr ll))
)
(setq desc (ade_projgetinfo "LL84" "description"))

Most importantly, that code uses functions only exposed in AutoCAD Map, Land Desktop or Civil3D.  If you are not using one of those verticals, you will not be able to get it to work.

If you are running MAP/LDT/C3D, there is a missing function "LABEL" (and possibly more), but the label function should not be hard to reproduce.

I'm using Map and Civil 3d.

Thanks, just what I needed.

Works just fine for Autocad Map.

Just notice: lat and lon must be swapped

I need this for a project.... so....

Didn't need the description on every tag. Also I am picking established blocks, so you may want to place a point on the pkpt (pick point) or draw a line from the pick point to the tag.
