Curve data lisp doesn't work with polyline segments.

[jpcadconsulting347236]

Hi folks,

I got this lisp that inserts a block with curve info (start and end points, radius, length) after selecting an arc... and it works great (thanks to - if I remember - Lee Mac, Tahrwat, and a few other I'm sure).

It works great when selecting single arcs, but it does not work when selecting polyline segments. The routine doesn't crash, but it populates the block attributes with "####" as it's not pulling data from the polyline segment properly (or at all actually).



Here is the code. Any help is as always greatly appreciated.

(defun c:CurveTagTEST (/ ent obj CL SCL CID SP EP RAD AL)

(setq CL (getvar "CLAYER"))

      ((= (getvar "INSUNITS") 2) (setq SCL 0.08333))
      ((= (getvar "INSUNITS") 4) (setq SCL 25.4))
      ((= (getvar "INSUNITS") 5) (setq SCL 2.54))
      ((= (getvar "INSUNITS") 6) (setq SCL 0.0254))
      (t (alert "Current DWG set to non-standard units.  Check UNITS settings"))
)
