Is it possible for a lisp routine to measure line length accuracy more/less precise than AutoCAD itself when the precision in AutoCAD is set to its highest? The reason I am asking, we have a lisp routine that exports line lengths to an Excel spreadsheet and separates into differing categories based primarily upon line length (as far as I know). Although I am sure line entities have specific qualities other than length that could cause them to list differently (i.e. - handle, start/end point, etc.), are there any other aspects of a line entity in AutoCAD, other than length, that could cause it to somehow affect the listing of the lines length through a lisp that would cause this anomaly?
Many thanks!
