Hi,
currently i found on the web , this lisp to draw Road profile or any other profiles by the lisp that contains two commands :
1- " NGL " : To draw natural ground elevation in terms of station and elevation from an excel sheet with a Datum .
2- "PGL" : tO DRAW DESIGN ELEVATION from excel sheet too , with same datum.
the lisp states an error message "error no function definition , (ACET-STR-FORMAT ) after loading " NGL" and entering datum , BUT it work with " PGL" without any error ... ??!!
i use AutoCAD2012 ? , what do you think that the problem is ?
lisp and excel are attached .
