All the details are avialable in the attached file,
it would be very nice of you
if you can help me generate this curve table by selecting two end points of the curve

Would you be willing to learn how to do it?

YES BUT HOW??

Good!

Ok, the first step is to create the command function and get the arc. You will need to use the Visual LISP functions defun, setq, and either entsel or ssget and ssname. The help files ought to help you understand how to use those functions.

Open the help files (F1, Developer's Guide, AutoLISP Reference) and read up on the functions I listed.

defun is how you will create a command-line function (think "command"). The function's name needs to start with C: to be recognized as a commnad-line function. Don't worry about declaring arguments/variables at this moment. The help files show how to use this function.

setq is used to store data in a variable (called a "symbol" in the help files). You will need to use variables to store data such as the arc the user selects.

enstsel is one function that allows the programmer to let the user select an object in AutoCAD. Or you could use ssget to make a selection set of what the user selects (the advantage being that you can "filter" what the user selects, to force them to pick only arcs).

So you need to use defun to "name" and start your program and setq to store what the user selects via the enstsel function.

Code:

(function? C:CurveTable ()
 (function? inpPick (function?))
 (princ)) ; clean exit (most programs end with this)
