This document contains AutoLISP functions for analyzing and extracting data from 2D and 3D objects in AutoCAD. It includes functions to calculate distances between 2D points, extract coordinate data and write it to a file, analyze spline curves on polylines and write curve data like radii, angles and lengths to a file. The functions prompt the user for input like selecting objects or points and allow controlling snapping options.
