I am trying to create an AutoLisp program which will create geographic grids in model space inside a closed polyline at user interval in deg mins or secs and also the markers on a polyline at user specified geodetic distance etc..
For this I want the user to select the available coordinate systems which I can get from ade_proj* functions,
and when the user selects the coord system I can get the code of the selected system but not the details required such as Equatorial radius and polar radius which are useful for the above said functions.
Thanks
